Below is Fin-Lee, my PetCo pick. The first pic is the day after I got him home, and he's somewhat use to the tank, a Spec V. He was a dull little fella, and not wanting to do much. He'd stay in the one corner, not too sure what to do with all the fin room. The second pic is after 3 weeks of TLC and a good diet. His colors have come out, and fins grown. He swimming all over, and investigating anything and everything. His personality has really come out...he's a tease at times...I'll look at you, but you can't look at me. He's even greeting me when I get home.
I know it's a store, and the poor things are treated a product, but come on...respect and treat them as you would a dog or cat.
