So... I swear this is exactly what the yellow one looks like.
collecting endangered species?
not good.
Sounds like a stone cat, they can be locally plentiful but generally rare, it pays to know what you are collecting and where. Do not release them back into the wild! If they are rare or endangered it's too late releasing them into wild could introduce disease, never release captive fish back into the wild...
100% yellow bullheads. They'll get about 10-14", hope you've got a 125g or more for the two of them when they're adults. Great fish to keep, just large and messy.
