I have a 20g tank with 2 Flame Red Dwarf Gourami and a Fiddler Crab. My Gourami get along great for the most part, with each having "their sides" of the tank. My aquarium is currently at about 80 degrees which I understood to be the higher end of what Gourami might like, yet the fish who claimed the side with the heater is acting oddly obsessive about it. He stays within about a centimeter of it at all times often floating right next to the heater near the top (where I'd assume it is warmest).
So I may be a worrier, but is my tank too cold for my fish? Or do Gourami sometimes develop intimate relationships with inanimate objects in their aquariums? I want my fish to be comfortable at all times so if any of you Gourami owners can give me some advice on that issue!
One more question for the experts.. Do Gourami and Cory Cats have any problems sharing a habitat? My tank is starting to show tiny bits of algae so once my LFS
helps me decide I'm ready for some algae-maintenance friends for my Gourami, I'd like to add something. I still have a lot of reading/asking-all-of-you before I pick out any buddies for them though. One problem for Corys might be that I have regular aquarium gravel substrate..
Thanks in advance for any help you can give!
