I'll take note of this! My male had salt put in his tank because it benefited the plants I had in there, and my female had salt put in hers because she was sick for a while and lost her color - seemed to be doing better since there was salt in there. I'll lay off on the blood worms, I do have some Omega One pellets. As far as a heater, I have had trouble with them before, getting the water too hot and stuff but I'll try again. How can I help my female? I haven't seen her cause I haven't been home but if she's still alive do I just let it take it's course?
