I have a 77gallon tank, 10 zebra dan., 10 copper rasboras, 2 opaline gouramis, 4 cory, and 10 rummy nose. The rummy nose tetra's were added last Saturday. Nitrates were 0.1 g/mL, pH 7'ish, and ammonia negligible. Overnight (sunday morning), smaller rummy nose developed internal white "blobbing" (for lack of a better word!). Most small rummy nose had it internal and directly inferior to dorsal fin. 7 days later, little progression, some smaller rummy nose have white coloured interanl organs. Fish in tank it was purchased from show no signs of same problems. Fish behavour appears normal but I'm inexperienced! Please help!!
I have a heater in the same room as my tank, will it mess up my water/
I also have the very cheap temp messuere ( it is a strip of plastic that sticks on to the out side) will a heater mess up the reading?
My water is cloudy and it is a new tank is it new tank syndrome?
So I went and got a 20 gallon tank, and used this site to set it up and figure out what to stock it with. I let it cycle for three days and got my fish today. I got one dwarf gourami six neons and four panda corys. And there all ok except the corys and one neon. Only one of my corys is still around and i dont know whats wrong but he's not doing well. What should I do?
Lots of water changes as your tank is going through a "fishy cycle". Your fish are suffering from elevated levels of ammonia in the water.
Read the sticky on cycling, and consider posting further questions in separate threads in the general freshwater or freshwater newbie sections. That way more people will see them and be able to respond.
