I'll add a small amount of detail to what Bas Pels said. Kale is just a variety of cabbage. You could probably use cabbage as well, but I tend to go with the darker green plants when I feed leaves.

Next time I get any, I'll try this. Of most significance, finally, someone had discovered a good use for kale. :)) Thanks! I raised a lot of grasshoppers on kale during my dissertation. I killed some with iceberg lettuce. I just sort of transferred that experience over to otos. My theory with the l...

Darrel, thanks for this information. Once I read it I made a note to get a zucchini on the milk run and got it. But disaster stroked one I got home today, 4 of 6 Otos were dead. I got them yesterday and died today. I feel sad and angry, didn’t last 36 hours. Tomorrow I get 4 or 6 more. Thinking som...

What I don’t know is the species. I took one quick photo is not the best but can any one tell what species they are? Looks like Otocinclus vittatus . That's also the most commonly sold species in the USA. I've had good luck with mine using a suction-cup clip that holds kale leaves to the side of th...

It I had used mineral water to raise Triops. But I don’t know for the fishes, I guess it would be fine since we drink it. We also do fine drinking chlorinated water, but fish don't want it in their gills. I wouldn't be surprised if fish that like hard water could deal with mineral water, but soft-w...

The only problem is her left cheek spines are ripped out of head and angle 45 forward - can see (cheek end ) of defleshed white boney part of spine like a ball ( like on a human bone ball/socket) the flesh is mostly intact, its just like the ball has popped out of cheek socket. I'm trying to envisi...

I see, so you get pure water that you have to prepare by adding what you just removed from it before using for freshwater. Now I understand what is does. It's mostly used for: 1) Really terrible water, where you need to take out lots of bad stuff and re-add only the good stuff (like in this thread)...

I have not much to say about the subject of RO. I don't really know much just that people say is good. Can anyone tell the pros & cons. RO water is, effectively, extremely pure water, as reverse osmosis removes basically everything but the water. (Most RO units are actually RO/DI, at least the ...

Wow that's a lot of crashes! I have a couple really small tanks, 2.5 USG, so I might just stick one next to the larger tank with a handful of daphnia in as a precaution. Thanks for the tip! I don't think I actually had nine separate crashes as the bottle that survived was also not very close to the...

I've started off a daphnia colony in a spare tank next to my sump, hopefully I'll be able to maintain enough numbers to feed them once a week or so. I've managed to keep Daphnia going for the last year, but I always have colony crashes. I've started splitting the colonies out, with a few 2-liter bo...

Is a water cooling system using a fan, a radiator and a chip called a “peltier device”. This chip once you supply it with electricity cools one side and heat the other. It cools to freezing leves. On the computer you cool the cpu and then run water tru a water block on the heating side pumping the ...

I haven't dissected any large loricariids so I'm not sure what a healthy one should look like but I have dissected a lot of fish, so here are all of my thoughts. Sorry in advance that they won't be much use. the belly was sunken, eyes extremely sunken, and gills pale The pale gills seem odd. Gills a...

Thanks Eric, do you have any idea what those single celled looking organisms might be? I'm guessing they are just something naturally occurring as there were very low numbers I think I only saw 3 from two skin scrapes. Not much additional information here, but the way they move indicates that they ...

This thread: viewtopic.php?f=6&t=42862&start=120 suggests that some snail species actually help cory eggs hatch. (Note: some. Assassin snails are probably egg-eaters, for instance.)

I don't have any direct evidence about pleco eggs, but there's a start.

Thanks, I do understand that and the primary purpose of the wavemaker are for surface agitation to increase oxygenation. I was just hoping to give them a flow pattern that they would prefer - e.g. marine species hide amongst reef rocks but prefer random or wave patterns over constant flow Marine sp...

Good luck and be careful if you do use an angle grinder, thick gloves and goggles are a must! If you're getting dust off of that I'd go for a mask as well. Stone (and plastic) dust has a nasty tendency to get into your lungs and stay there for the rest of your life. (Wood dust can be broken down by...

It is usually associated with doing a large water change and forgetting to use water conditioner. I have done it more then once over the years. You can add an immediate heavy dose of conditioner. Some will make it and some will not. "Sensitive" fishes like many glass cats, small tetras, a...

So this is being posted in Asian catfishes because I first observed this in a glass catfish but I've now observed it in a sparkling gourami in a totally different tank. The condition is as follows: the fish begins to lose "balance", and while swimming often begins to rotate around its long...

Hi all, General "therapeutic" use aside, the square-cube rule would make me think that salinity would be much harder on small freshwater external parasites than larger freshwater fish. It would be bad for everyone, but possibly fatal for parasites and uncomfortable for fish. You may well ...

Gravel, airstone, water changes, and stale vegetarian pleco food disks is how I raise blackworms (not just maintain them).

These fish have evolved in water where the conductivity values are in the 10 - 100's range, and the Na+ and Cl- ions concentrations are vanishingly small, why would a salt addition be therapeutic? General "therapeutic" use aside, the square-cube rule would make me think that salinity woul...

I've seen this behavior from cories and glass catfish. On the other hand, the electric catfish in my lab always hides for some time after a water change. This probably depends some on relative temperatures and conductivities. I see the biggest activity changes in the glass cats when the water is als...

My (rather minimal) experience suggests that the break point is whether an oto can figure out what to eat in a tank. Some seem to take to algae wafers and vegetables and some don't. I seem to have the best luck with getting otos to accept large vegetable leaves and introduce "weirder" food...

Anubias would be fine, but java moss might work too. Java moss is also basically bomb-proof, so if your Anubias is staying alive Java moss will stay alive, too. I see you're outside the US, so in case the names are different here's the Wikipedia article with the several scientific names Java moss h...

Hi Mark, I think the device you bought will probably work better than fine, but I wanted to point out that transistors will also solve this problem. You want a transistor that is "off" (does not allow current through) when the biasing voltage is on (i.e., there is power in the house) and s...

I think that two of the females BN Super Reds may have been fighting yesterday, they were acting a little strange. Today one is lying on its back. Moved the fish with a net and it swam away. Any reason for them to lay upside down. Exploreman My BN sometimes lies on his back directly under a surface...

I have to say that this looks more like "Rhamdella zelimai isn't Rhamdella" rather than "Rhamdella is a lie".

keeping any live animal captive, to some degree, is cruel no matter how you try to justify it. The basis for this ethical statement appears to be because you said so. Again, this idea seems to be based on the idea that freedom is of inherent value, which I disagree with. concrete is not living no m...

So I was largely going to avoid this debate because you can't have profitable debate without some shared ground to start from and when it comes to morality there is very little shared ground in the modern world, but I do think it's worth pointing out some of the assumptions here so you can understan...

Thank you for the warm welcome Eric. Everyone is getting along so well it feels like they are just in the ocean enjoying the company of each other. Hi Belle! Welcome! I've not been a member for all that long (at least compared the some of the Ancient Ones around here) but the amount of knowledge pe...
