I have had this particular goldfish for about 2 weeks. At the moment he is in a 40 gallon tank with 1 other goldfish. In the past maby 5ish days, every time I go and check on them hes always bottem sitting, but when ever I put his regular food in the tank he starts swiming like nuts to get all the food he can. I havnt noticed white spots that would indicate ich so far, but I think there might be slight cloudyness on the verry edges of his tail, the size of the small spots havnt grown and the tail hasnt begune to get shreeded. A few days ago I did about a 30-40% water change and he is still bottom siting.
Any ideas?
