DOH!! The fish are not actually mine, although I look after them a bit... I bought a big new tank and left instructions to just clean it out but found when I came home from work the fish were inside it!!!!!!! So a bit late for the no new tank thing...

thanks for the advice, I will try the peas for a few days the next time I am over, I guess its not lookin too good though.. he/she is pretty big!
