I have a sailfin pleco who is or seems to be getting worse. I thought it was white spot so treated for that but the about 50 cent spot was white but lifting the kind of like scales of his head and leaving a small indent he hasnt been moving much just staying in one place night or day and today i noticed a rather yuck smell coming from tank, so did water change cleaned out filter and within a short time the smell has come back so ive quaratined him but unsure what else to do he had been fine till i got this filter and i dont really know how the filter could have caused this and there really is a bad smell coming off his water in the quarantine tank and ideas sugestions please please......

Hey chickiejo,

From memory you are in Upper Hutt, send me a PM if you want me to come around and have a look, will be able to give much better answers if I can see it in person. I work from home so I'm always around.

When you started up your new filter, did you disconnect your old one?

Only advice for the moment is to make sure the water in his Q tank is as clean as possible, if you can smell anything other than clean water or dirt, then do water changes of a similar temp. Redspot Plecs are one of the most hardy fish around, so chances of recovery for the guy are quite high.

Good luck,

Jono

if hes eating what are you feeding him? what media is in his filter?

sounds like it might be fungus? when that lifts off it leaves a raw patch.

best of luck
