Petco had a manager special on what they call a "vanilla lobster" today, and I couldn't help myself. I brought home a male, he's about 5" long and pure white. He was kept in a tank with cichlids and another crayfish, so he's missing one feeler and a few toes, but overall looks pretty good!
Right now he's in a planted, fully cycled tank and doing pretty well, started to look around a little bit and nibble on some plants, and did a bit of redecorating; "No no no, I assure you, this specific piece of gravel looks much
better right here!" Then he retreated to the corner and started grooming, so I think he's doing alright.
The only problem now is that I have no idea what species this guy is. He was literally just labeled as "vanilla lobster," and I only know he's a tropical, fresh water species. I figure most lobster/crayfish care is the same, so I have a good aeration system going in the tank, gentle filter, live and silk plants, and am feeding algae wafers, shrimp pellets, catfish wafers, and live minnows.
