Sick Krib

[sarah86]

one of my kribs isnt too well. he keeps hiding behind the pump and when hes out hes not using his tail fin hes just keeping it bunched together rather than using it to swim. he seems a bit lifeless too. i know the female is a bit of a bully and chases him so i dont know if this is the reason, but we lost a cory tonight whos eyes had bulged then one fell out. im concerned that it may be the start of something, i briefly found some stuff on the eye falling out relating to TB and then also found stuff on fin folding, could this maybe be the cause? we have had these fish a week and im worried they may have infected the tank with something they picked up at the shop

anyone got any ideas on this? hes still going, sitting on top of the pump with his tail fin folded and not doing much. would really appreciate some advice
