Lol I'm not really that good with Vieja identification yet either...Morbid - or I think she uses straightjacket on here? - is the person to ask for sure. But to my not-so-experienced eye, they do seem to be blackbelt babies.
Sorry to hear about it.
I bought my BB's as a young unsexed pair. It just didn't work out. They're very aggressive in general and even more toward one another. That really made them unappealing for me.
When I have a huge tank of several hundred gallons or a pond I'll want to keep one again.
I guess you can see where I am coming from as far as the body shape goes... Here's a photo from the current photo contest of a severum that looks extremely similar in body shape, which leads me to believe that these fish (mine) are a hybrid.
I don't think they're hybrids. Just deformed.
They don't show any non-BB characteristics besides the shortness of the body and I've seen short bodied Xenotilapia, mbuna, eartheaters, livebearers, tetras etc. that were not hybrids.
