It looks like an abscess. The photo is not very good, but the abscess is the pink thing growing from its mouth. Could anybody give me some advice about how I could help? It seems like the fish still can eat, but it is bigger and bigger and I do not know for how long it will be able to eat. Elektra 2009-04-25
