Hi Eric,
Congrats on all the babies, thats awesome.
Can you use algae wafers to feed the babies? Seems like they might take to that and Ive seen folks who breed Ancistrus use them? What do you feed the parents?

Before I turn to algae wafers, first I'll try the algae-coated plastic plates I'm preparing with some of the green water from the tank (as recommended by Jeanne), and then my next option would be algae flakes. I'm a big fan of the SeaChem NutriDiet Chlorella flakes, the Fluval BugBites Spirulina Formula flakes, and the NLS AlgaeMax Spirulina foods (the latter is a pellet, not a flake). These all have algae as their first ingredient instead of fishmeal. The other food I like to use with fry is uncooked Repashy powder, just saturated in the water and allowed to settle as a dust. In general, I find babies do better with flakes I can crumble between my fingers and powders rather than with big pellets.
All that said, it's my understanding that is more of a biofilm eater and that they'll flourish on live microworms. So my first foods are the live microworms 2x per day and the algae coated plates. But I have lots of algae foods on hand, so if the microworms aren't cutting it, I have options.
Also another update. But the end of the work day, I had caught even more babies. I now have 115 fry in the breeder box.
Cheers, Eric

Re: Rio Itaya black Rineloricaria lanceolata spawned
I dropped into work today to feed the babies. Only two days after returning dad and his bamboo cave to the aquarium, I find this!bekateen wrote: ↑24 Feb 2023, 19:00 I just put the bamboo pipe back in the tank yesterday after all the eggs hatched in the breeder box, and already there's a male and female back inside the bamboo. This male looks smaller than the male that spawned before. I'm not sure he'll pull it off or be able to keep a bigger male from taking over the bamboo before he can get a spawn done.
Dang they're horny!

Re: Rio Itaya black Rineloricaria lanceolata spawned
I have six specimens of this species, two large males, one smaller male, two large females and one smaller fish, I think female. With this second spawn occurring so quickly, I thought this male looked smaller than the first male to spawn. But now, comparing the two spawn photos and looking at the facial markings of the dad, it appears to be the same male.

Re: Rio Itaya black Rineloricaria lanceolata spawned
I don't mind at all. So far, I had one dead in the first couple of days after hatching, and then last night I found one dead. That's it, only two dead over one month, out of over 60 fry surviving still. Those babies are nearly 25 mm SL now. Using these Fluval breeder boxes, this is probably my best survival ever for Rineloricaria. In the blue Imagitarium boxes, and even in the better German Breeder Rings, the microworms fall through the bottom, so the babies get less time to eat at each feeding.sturiosoma wrote: ↑26 Feb 2023, 12:20Thanks for the pics Eric, and just what I expected to see a breeder box full of wall hangers, and if you don't mind my asking what would you estimate your survival rate was with your eigenmanni spawn you reported on a while back

That's exactly what I did to grow the algae on the plastic plates. I have a breeder box with plastic plates inside in a greenhouse tank to culture algae. I put multiple plates in there so I can pull out a different plate every few days.
But I don't put the babies out there for a few reasons. First, the greenhouse is not thermally stable, and with new babies (especially with a first-time spawn for me, regarding the lanceolata), I want them to have a stable environment. Second, on the advice of other whiptail breeders and based on my experience with eigenmanni over the last couple of years, microworms are a first choice food for these fry (unlike, for example, other species that might prefer algae over an omnivorous diet), and I have a stable cultures of microworms both at home for eigenmanni and at work for lanceolata. Finally, I feed the fry at least twice a day, but I only get to go to the greenhouse once a day at most; again on advice from other breeders, a constant supply of food is critical for food survival, therefore I keep the fry close to me at work.
From your questions, I'm inferring that your experience says algae is the "go-to" food for baby whiptails; is that right?

Re: Rio Itaya black Rineloricaria lanceolata spawned
No not algae alone but from my experience with my eigenmanni spawn they spend a large amount of time on the walls of the breeder box, so if the entire box had a growth of algae they could feed off that along with the micro worms and have you observed their nighttime behavior, do they come off the walls and go to the bottom to feed

Re: Rio Itaya black Rineloricaria lanceolata spawned
Yes, after lights go off (and in morning when I leave them alone), they do come off the walls and go to the bottom to feed.sturiosoma wrote: ↑26 Feb 2023, 22:56 No not algae alone but from my experience with my eigenmanni spawn they spend a large amount of time on the walls of the breeder box, so if the entire box had a growth of algae they could feed off that along with the micro worms and have you observed their nighttime behavior, do they come off the walls and go to the bottom to feed

After about 2 weeks of age, my eigenmanni spend most of the daytime under the oak leaves. Only about 25% of the fry are on the walls of the tank. When I awake in the morning and first turn the room lights on, almost all the babies are out on the floor of the breeder box looking for food. Then when I add the food, it scares them and about half scurry under the leaves, then come out later.

Re: Rio Itaya black Rineloricaria lanceolata spawned
The second spawn, if following the incubation schedule of the first spawn, should have started hatching overnight Tuesday and finished overnight Wednesday (March 8 ). But no. The eggs started hatching overnight Wednesday and are still in progress today (Saturday, March 11)! So far, only about 30 eggs have hatched as of today, and dad still has a lot of eggs. If they finish hatching overnight tonight, it will have been 15 to 15.5 days for hatching! Dang that's a long time. Aquarium conditions haven't changed, so IDK why they took so long!

Re: Rio Itaya black Rineloricaria lanceolata spawned
I left town for 5 days on March 15; at that time, the dad with spawn #2 was still sitting on A LOT of eggs, even though there were plenty of babies already hatched and swimming around the box. I left a student to take care of the fry and watch for dad to finish hatching the eggs while I was gone. He reported that dad finally finished hatching eggs on March 16. That means it was 19 days from the time I first found eggs on Feb 25 until we found all the eggs had hatched. Given that the first batch hatched in 11-12 days, that really makes me think this second spawn is two spawns a week apart with the same dad in the same cave. But is it with the same mom or different moms? I have 3 males and 3 females, so...???
Today is one month since the first spawn hatched. Both spawns are doing well.
I don't want to sound greedy, but I was expecting the parents to have spawned again by now.

Re: Rio Itaya black Rineloricaria lanceolata spawned
This morning, after I fed the babies from the first two sets of babies, I was rethinking the weird dynamic of the second spawn:
Now I'm really wondering if there were two spawns with the same dad in the same bamboo, about one week apart. I don't know the max clutch size of Rineloricaria lanceolata, and our BLOG input system only allows a maximum of 100 eggs - any count over that is rejected. But I had about 115 fry from the first spawn so I know the clutch size is at least that. I also know with many species, subsequent clutch sizes increase as the females grow in age and ovary size, so I don't know if 200+ babies reflects two spawns of about 100 each, or one giant spawn of over 200 fry.
If there were two spawns with the same dad in the same bamboo last time, then it would mean the spawn from yesterday is spawn #4, not #3.
Does anyone know the max clutch size for this species? What's the biggest R. lanceolata spawn you've had or have heard about?
Cheers, Eric
- The first eggs started hatching on day 12 of incubation, a day later than the first spawn (that in itself is no big deal). However,...
- By day 17 of incubation, there were already 60-70 fry in the box and lots of fry had escaped the box. But there were still LOTS of unhatched eggs.
- It was 19 days until all of the eggs finished hatching.
- Today I attempted to count the fry. There are over 200 fry (!) in the box, not including fry that got loose in the tank (which I didn't attempt to collect, since I have so many already in the fry basket, not to mention the 100 still in the box from the first spawn).

Re: Rio Itaya black Rineloricaria lanceolata spawned
Hi Jeanne, so far, I've pulled out only 3 or 4 dead from the first spawn. I imagine a few more have have died, but I haven't seen more dead bodies from that box and I still have at least 100 of the one-month old babies. So survival rate is over 90% at this time.

Re: Rio Itaya black Rineloricaria lanceolata spawned
Was that second spawn actually two spawns at once? The mystery may be solved! Dad's already on eggs for two days, and another female is back in his bamboo laying MORE eggs!
Cheers,
Eric
Rineloricaria lanceolata: One male. One bamboo pipe. Two spawns at once? TWICE?

Re: Rio Itaya black Rineloricaria lanceolata spawned
About two weeks ago, I had to move the oldest baby out of the breeder box, because I needed the breeder box for the latest spawn which was going to hatch at any moment. I put the oldest babies, along with some baby , in the greenhouse, in a 60 gallon breeder. Today, the Rineloricaria fry are about 2 months old and the biggest one I saw today was 22mm SL.
The two younger batches of fry are still in breeder boxes in my room and doing well.

Re: Rio Itaya black Rineloricaria lanceolata spawned
Here's one of my largest (but not the largest) Rio Itaya fry.
They've been growing in a 60 gallon tank in a greenhouse since mid-April. This F1 specimen is just over 3 months old (three months and one week old), 53mm SL (nearly 70mm TL). It has a beige base color, blackish markings and some green iridescence. Lovely!
Remarking on their size, I gotta give a big shout out to growing babies in a big tank in a greenhouse, where (I think) the algae and microfilm growth from greenhouse natural light helped. These fry are more than twice as big as the largest fry of same age reported in the only other BLOG with size data, and they're much bigger (at least 1 cm longer) than the similar-age fry that I grow at home.
Twelve of these fish, along with twelve L052, six `big spot`, seven Ancistrus aff. bodenhameri (), and twelve , are going to auction at the FIN-DIG 2023 event this weekend in Sacramento, California.
Cheers, Eric

Re: Rio Itaya black Rineloricaria lanceolata spawned
About 5 and a half months old, over 71 mm SL... and this may not be the largest fish (as you can see from the photo, the water in their tank is VERY green; this fish was just hanging on the glass so I took its photo).
Cheers, Eric
I have another group of over 80 fry, now a month old (they hatched in the last week of June), in a breeder box.Cheers, Eric

Re: Rio Itaya black Rineloricaria lanceolata spawned
This group of fish keeps plugging along. I had a spawn at the end of June, which hatched in early July. They're about 3 weeks old now and doing pretty good. Also, three or four days ago I discovered another dad on eggs.

Re: Rio Itaya black Rineloricaria lanceolata spawned
Looks like your raising lots of fish successfully! Since you have so many babies, I suggest you grow algae on 200mm x 20mm x 20mm lengths of hardwood stakes instead of plates. (Most garden suppliers sell stakes). I drill a hole at one end and use coat hanger wire to hook onto tank sides and algae tank. Instead of a tank, I use clear 2L plastic coke bottles and can fit 6 or 8 stakes per bottle. Have around 30 bottles on ten day staggered rotation, rob and re-start 3 bottles each day. A small pinch of soluble fertiliser per bottle to encourage lush growth. The stakes grow biofilm as much as algae.
The very first few days of first feed, I drop water level in growout tanks to a few centimetres water and lay the stakes horizontal as they don't forage far. I used to use decapsulated artemia but prices sky-rocketed. Once a couple fish start eating, the rest copy.

Re: Rio Itaya black Rineloricaria lanceolata spawned
These Rineloricaria are more carnivorous. I'm sure they eat some algae, but I'm growing them out on live microworms. When they're a little bigger, I'll move them to a greenhouse grow-out tank that looks green with algae, and then I'll supplement the algae with shrimp flakes and later shrimp pellets.

I came to a similar conclusions back when I was breeding my wild caught Sturisoma spp.bekateen wrote: ↑05 Aug 2023, 04:47 These Rineloricaria are more carnivorous.

I think algae, diatoms and detritus are eaten incidentally in their search for higher protein foods. I consider these fish to be primarily predators of small aquatic invertebrate eggs and larvae.
I had very good fry survival once I relied on primarily earthworm sticks and chilled, live or freshly demised Artemia nauplii stored in clean brine in my refrigerator. These foods were my secret sauce.
I'm sure surprised at what seems to me, large sized spawns of such large eggs from a fairly small species. The really deserve to be a more popular species. Perfecting their culture would really help them to become more available and it looks like you're well along that way.

Re: Rio Itaya black Rineloricaria lanceolata spawned
Took some of my Rineloricaria lanceolata fry to my club (Sacramento Aquarium Society) today when Andreas Tanke visited to speak. The largest fry I brought, now 6.5 months old, was 74mm SL. They are growing quit nicely.
