This water thing can be pretty annoying sometimes. I've always kept cichlids and they've been fine, in fact they do pretty well, my fry are growing quickly, other the other hand these bettas just hate it and it doesn't do much for em.
Looks like I'm gonna have another batch of eggs from my cons tonight. If anybody is interested pm me. They have half black half pink. Unless some are marble aswell but I can tell at this stage.
