Thanks for replies, yes Dave Rinaldo that the one i thought it was. I must have just held it in the right way. Even dead the spines can poison. Lots of North American ictalurids have serious pectoral fin spines, but are often handled without incident. This is common enough that I know several fishe...

I know not just any slate is safe to put in a fish tank. But i have heard that if its been out of the ground it came from for a long time it is safer. I have slate (that i will add a photo of later) that is years old, has been just laying around my mums garden. If i clean it good and even soak in b...

Hello all. On the thread Bristlenose Morphs and Breeding we discussed whether there was any comprehensive dataset on the genetics of bristlenose breeding (as there is for, for instance, corn snakes). The answer seems to be no, there isn't one. But this is PlanetCatfish, and so we can probably put to...

There is a post somewhere from a long time ago, that was where I remembered the "three different types of albinism" from, but I can't re-find it. Milton Tan (@Suckermouth) was going to write an article on Bristlenose genetics, but I don't think he ever did. I suspect I can track down info...

Do we have a good genetic explanation for bristlenose morphs or is this uninvestigated? I ask because I suspect that this forum would be the place to gather useful data that would get us closer towards a good genetic hypothesis.

Hi ! If albino and super red are carried from recessive genes its not possble their offspring to be original grey - black color ! Sure it is. They just have to be different genes. If the super red alleles are N (not super red) and n (super red) and the albino alleles are D (dark) or d (albino) (min...

I had a similar problem with some home-made food, which smelled like (and I quote my wife here) "Satan farted and then it congealed". I now heat water in a pot on the grill outside (the home-made stuff needs near-boiling water). In cold weather the congealing part happens outside on the sc...

I don't have a lot of advice, but I can't see how the net will fall off on its own safely. It won't degrade fast enough, which means it will only come off by catching on things and being pulled, which may worsen the damage. There are ways to sedate fish (I've only seen them used at extreme levels fo...

What happened with the silicone glue? Was it that the glue didn't adhere to the acrylic? I've seen plastics attached to glass pretty well (obviously, tank frames work this way). Can you find a flat edged, slotted plastic strip to clue against the glass? Hard to tell. By the time I found it the sili...

I've got an idea for a 20 gallon long that involves removable barriers across the length of the tank. I want to install mostly-permanent "grooves" (I'll be installing the double short dividers that make the groove, of course) on the sides of the tank that I can slide the barriers into or o...

Yesterday I was in the LFS (part of a much stranger story about a fish that hid out in a mostly-drained, shut down tank for a week) and I saw a school of Corydoras pygmaeus in the front tank (which they always have set up as a nano-tank, essentially). I'd been thinking about some cories for my commu...

German blue rams are small and only protect small areas. another thought is shell dewllers like the ones uarujoey had here is a video of them https://www.youtube.com/watch?v=hQgZb6U3iPw I love the shell dwellers, but my understanding is that they won't be compatible with anything but other Rift Lak...

Definitely going to plant this tank, both to help with water quality and to create hiding spots. The tank is right in a window, and there's no real way to move it, so I'm stuck with a lot of light and will want plants to compete with algae anyway. Because of this, I'm definitely thinking at least on...

I don't need spawns to survive - most don't in the wild, and the behavior is the interesting part. If some make it through the gauntlet (as they would in the wild) then that's just an interesting bonus.

Mol_PMB, am I correct that the Biotodoma, Farlowella, and tetras are all in the same tank?

Hey all, I've got a tank I'm nuking/restarting and I have a fairly specific idea about what I want the new tank to do but I need your significantly-more-expert advice. Background: when I started my current job there was an unused 110-gallon tank with full sump and media in the classroom I worked in....

Guys, Has anyone got a PDF of this they can share? I'd like to check the species I've got some pics of. http://www.mapress.com/j/zt/article/view/10010 Cheers, Jools I can get you one (after we finish Easter lunch here in the Eastern USA). I should have access to ZooTaxa through university databases.

I've had a Bristlenose for around 3-4 years but never really see him until the lights out yet I see plenty of people who's Plecs seem to come out for food or generally just hang about in plain sight in any case. It's never been a great issue as it's always a nice surprise when we do catch a glimpse...

I believe Malapterurus was described by Bonnaterre in 1788, so I think the authors are saying that Gmelin (1789) identified M. teugelsi as M. electricus. Well, if so, they sure didn't use any of the terminology that would make that clear. I agree that's probably the most sane choice, but come on - ...

The one thing I did notice is when there are too many fry in a growout tank they do not all grow at the same rate. Fish are not identical clones, they vary in a number of respects. Some fish in a group are more aggressive than others. The more aggressive ones will get more food and they will grow f...

*This paper states that Malapterurus electricus is a synonym of Malapterurus teugelsi . According to the Catalog of Fishes , these are distinct species and not considered synonyms, either of the other. How could this even be true? M. electricus is the oldest Malapterurus name, older than even the g...

Iridescence in animals is normally a structural effect, not a pigment. This means that the microstructure of the tissue creates the color. In colors produced by pigments diet can change the color by providing more or less pigment. In structural colors the color is more or less set once the tissue is...

Throw in the word "organic" and it's probably already here.

For a completely different, possibly stupid, way to make blackwater, I've thrown instant decaf coffee into the tank. The pros of this approach are that the room smells like coffee, it's cheap, and it's massively unpretentious. The cons of this approach are that the room smells like coffee, it looks ...

Well, that sounds uniform. Now to find/make/buy covers. I use greenhouse siding - the clear plastic with ridges/ripples in it. I totally stole this off a guy on YouTube, but the ridges allow you to insert cables under the lids easily, there's some air exchange, and they definitely reduce evaporatio...

Those would be high protein, so to follow MarcW's suggestion you should back off on those.

I can see all his ribs and am very worried. I would also find this worrisome but, pedantic note, loricariid catfishes are covered in armor plates across their bodies and so the internal skeleton isn't what you're seeing. (See, for instance, this lovely scan of a Panaque skeleton.) Still, that indic...

Eric - "I didn't post it there originally because it's been my understanding that publications typically get in that thread, not posters. I know there have been exceptions, but that's my experience." Good information is good information whatever the format. Hopefully this will be consider...

Look's like you are right. This latin name was printed on my receipt though. :- My Ancistrus cf_cirrhosus was labeled as Ancistrus dolichopterus in the store. My Otocinclus vittatus were labeled as Macrotocinclus affinis , and the week before the store had stocked some sort of loach in that tank, a...

I'm wondering if whatever is wrong with them is causing (stress or something else) them to release toxins from the glands at the base of the pectoral fins, then they are poisoning themselves? I THINK that catfish toxins are released by the physical mechanism of the skin around the spine being pushe...

I hate to play necromancer and raise this thread from the dead but I recently discovered that I had (accidentally) replicated some of the conditions that spawned this thread in the first place. I present this tale for your edification. First, what did I replicate? A heavily planted tank with deep su...
