Not really yet. In the second picture, the big red looking one on the right, I've seen that one go from a deep maroon to a light grey body within a matter of minutes, so I think hes practicing marbling haha. They are all pretty consistent with these colors so far, for weeks now. I'm hoping they start coloring up soon. Some have fins just like their mom with the white body so hopefully that's a sign that they will look like her!
Haven't had any deaths either, aside from a couple who over ate right after I got them on frozen food and crushed nls pellets. They just didn't know when to stop...but I've solved that issue thanks to a suggestion from someone on Facebook. They are very interactive now too, anytime they see me they swarm in one spot together. They don't do that for anyone else, just me! Cause I feed them lol. I also haven't seen any deformities either thankfully. They're doing great!
