OK I have 2 blue powder dawrf gourmis in my tank. I think one is dead cause I havent seen it all day. and my other one is sitting at the top corner of the tank sick and not eating. he is very skinny now and not eating. I just had my black molly in my the same tank have Ick. so i raised the temp to cure it and it worked but now my gourmis are sick. I checked my water and all seems good. I feed them a very wide varity of food. I keep the water clean. I have had this tank for about 1 year now and all of a sudden I am having so many problems. Can someone pleeease help me with my tank so I can figure out the problem I am having. thanks
