I think I have a problem.
I noticed about 3 hours ago, that my clown fish is doing this strange twitch to one side. He has been doing it on and off for about 3 hours. It seems that he does it more when I am near the tank. He also seems to be nipping at the glass. He has no odd spots or anything on him. Does anyone know what this might be? He seems to stick to one area and do it. It is a little crater down by where my diamond watchman goby lives. Anyone ever seen this behaviour? Does it indicate anything?
Also my goby got a blackish spot, about the same time. But it seems to be on the inside of his upper lip, and does not look like any ich I have seen on the net. It kind of looks like he bite something that cut him.
Could someone post some high quality, good pictures of ich? I have been unable to find any on the net.
I checked all my params yesterday, and everything was perfect.
