The one that already died was bloated and had stringy poo, I orginally thought constipation but peas didnt make any differene and it died in 2 days. Tank is 60 litres, there is one male dwarf gourami, 5 neon tetras and 2 featherfin synos (these are very small at the moment and will be rehoused when they get bigger) stats are 0/0/30 (our tap water has 25 ppm nitrate) They get fed blood worms, daphnia, one type of 'crisp' type flake food, catfish pellets and catfish algae waffers, peas, on a rotaing basis.
Its really difficult to actually see what it is on the fish, and he wont keep still for a pic! its bigger than a grain of ich, but difficult to see.
