Hi everyone
I have just joined this group and require some advice. I have 2 tanks (soon to
be 3)
and keep a variety of fish. I am having a problem with my sailfin suckermouth
catfish
who has developed some large grey skin patches. It almost looks like his skin
has lost
its colour and is becoming see through. He is eating (and excreting!) normally,
moving around OK and will display if he is annoyed.
Does anyone know what could be causing this? I've had him about 6 months and he
has grown to around 5". The water tests OK. He shares the tank with 2 zebra
danios
and 5 glowlight tetras.

Any help on this woud be gratefully appreciated as he is a beautiful fish and I
would
hate to lose him.

Thanks
Arla
