I'm concerned because his foot turned black overnight. I tapped him and no immediate response. The betta and bristlenose are both fine, but two days ago I used Seachem's Flourish Excel. I love this mystery snail. Never had one so big (bigger than a golf ball!)
I was told it was a cichlid but when I looked up pictures of cichlid species, I can't find any that quite look right. It's obviously not well taken care of and I want to take responsibility for it (I'm new here).
According to what I read tonight, when it comes to cichlid care, there are some basics all cichlids have in common but that really, each species has its own special requirements that's why I really want to know what species it is. Thanks!
