Oh I am fully aware that some are not compatible, the Balloon Molly is in the tank temporarily. As for the other fish, however, he reacts perfectly fine with them and no chasing is partaken with his tank mates. (Mostly busy staring at his surroundings xD.) As for being over stocked, I already configured with the site and I'm aware. There are 11 fish but with a 30 gallon filter and more percentage of the water being taken each week, it is completely fine :)

Your right! Its also weird that his tail does not completely separate like normal double tails. I always think he has like a heart tail. Nevertheless I think it looks cool like that 8)
Thanks for everyone who commented! I picked him up at PetCo (of ALL places) and I hope to get along with all you members :)
