Can anyone help me with this? I am pretty new at keeping fish. I have a 29 gal tank with artificial plants. Up until recently I had one dwarf gourami, 4 coreys, 6 rummy nosed tetras, 7 glowlight tetras, 6 grown platies, 2 baby platies, and 12 baby mollies. It's a long story on the baby mollies...I sold the 4 parents. Also 1 snail and 12 japonica shrimp. My problem is that several days ago I noticed a sick looking rummy....it hovered in one spot and did not want to eat. It died the next day. Two days later another rummy died...found it in the morning. Now one of the glowlights is hovering and it appears like it's gasping for air. The Gourami has white bumps on its body but not ich....just large white bumps. I spoke with the fish store and they suggested I probably have a parasite and should treat it with aquarium salt...1 tablespoon for each 5 gallons. It was also suggested to me that probably I will lose the shrimp. Does anyone have any suggestion or advice that I am doing the right thing? I don't want to lose any more fish. Thanks.
