hi everyone. as im sure you know ive had troubles with my sterbai cory who has a mucous (not sure on spelling) type infection. She has had it for a long time, but it wont clear up. She feeds normally but she isnt as active as the others. There is a pale layer of mucous on her flanks behind the pectoral fin. It never spread until i just noticed my female panda has a tiny bit on her now. I want to gt this sorted before i get the plecs because i dont want it to cause them harm. Ive treated with medicines before, whats the best to use? thankyou

Difficult to say without seeing it but it sounds bacterial. There are both gram+ (positive) & gram- (negative) bacterias so not all bacterial meds necessarily treat both types.

Could also be flukes (parasites) but usually that has flashing or scratching associated with it.

Sorry, even at full size that's not clear enough to give a definitive answer. Still leaning towards bacterial issue though.
How often do you clean the gravel?

looks fungal to me, but very hard to tell.
when i dont know what the problem is I first try a mix of both pimafix and melafix as these are natural plant extracts and can do no harm ( but with all meds make sure there is plenty of oxygen in the water like venturi or airstone)

Hi all,
Ok, I did have a problem with dirty sand so I changed it to gravel and I'm cleaning it every 2 weeks
Sand shouldn't be a problem, particularly if you have MTS and/or plants. I would be very dubious that even regularly vacuumed gravel intrinsically produces better water conditions than sand. The mulm that may develop on the sand substrate is not actually very polluting, and may actually offer advantages in terms of providing DOC and maintaining water quality.

Have a look here: <http://www.skepticalaquarist.com/docs/substrate/gravel.shtml>

Another point is that Cories usually do much better with sand, gravel is an un-natural substrate for most Cories (they feed with their barbels in the surface layer of material over sand or mud) and stops them displaying their natural feeding behaviour.
