Hi guys, first post in this part of the forum and I was wondering if anyone could give me some advice please.
I currently have a group of 8 various corys (4 peppered, 2 of which are quite elderly at 5+ years old, 3 bronze, two of which are fully grown albinos, and 1 adolfoi; the reason there is only one is that I can't find them anywhere). They are all very active and eat very enthusiastically. They're in a 202 ltr tank with very fine substrate which they love to bury around in. I was considering adding a few more bronze and peppered in a couple of weeks.
My problem is that we've noticed some really odd behaviour in the past couple of days. Mainly it's only the peppered corys that do this, but they'll stop swimming and just float upwards. They are completely motionless and look dead. Then they spring back to life and carry on as normal. I've also noticed (especially on the older peppered corys) that there is a white "fluffy" type stuff on their fins. It doesn't effect anywhere else on their body. No other fish in the tank are effected.
Stats are:
Ammonia: 0
Nitrite: 0
(Haven't tested for Nitrate yet)
pH: 6.4
Temp: 25
Tank mates: 9 female betta, 2 pearl gourami, 1 guppy, 4 dwarf cichlids + plus corys.
New additions: 4 dwarf cichilds- 2 Apistogrammoides pucallpaensis (1m 1f) and 2 Laetacara araguaiae (1m 1f). These guys came from a very reputable breeder and show none of the above symptoms either. I saw all the fish in their tanks before purchasing and there were no diseased or dying fish so I'm pretty confident that what ever this is hasn't come in from them. This behaviour has been going on for a little longer than when the cichlids where introduced anyway.
I change about 30-40% water weekly give or take a day.
No medications have been used in the tank.
Tank is heavily planted with bogwood, slate and stones (nothing sharp).
If anyone could shed some light on this I would be very grateful, as I'm especially concerned about the white fluff.
Cheers!
:EDIT: Had another close look and the white stuff is only on the four largest cory's- the two elderly peppered and the 2 albino. The others are babys, and the adolfoi is not effected either.
