Hey guys
We have a 500litre tank, been set up over 18 months with no issues.
Currently stocking
- 5 discus (Were 6...)
- 1 leopard ctenapoma
- 1 ghost knife
- 1 kribensis (were 5 but the other 4 paired off so are now in seperate tanks)
- 4 large bristlenose
Tank is planted, run off a sunsun external filter with uv purifier. Fed on a mix of discus bits, frozen bloodworms, tropical granules, pleco logs and cichlid sticks sometimes. 20% water change done every two - three weeks.
Tank stats:
PH - 6.8-7. pretty stable, have never tried to adjust it down
Ammonia - 0
Nitrite - 0
Nitrate - 0
About 5 months ago, two of the discus (the middle sized not the smallest) went quite dark. The started breathing rapidly and were almost jerky in their movements.
On advice from hollywood fish farm and the fisho dude at animates who had always been helpful to us, we got Adtape from the vets and dosed the whole tank. Had no signs of worms at all.
Dosed again 3 weeks later as fish still weren't right. nThey were both eating still and very active at feeding times.
Fish continued to get darker, and started to look skinny. Then started lying on their side in the corner of the tank! We thought it was the end, took a water sample down to the fish store to make sure everything was ok in case our kit was false reading. all stats good. did a 40% water change. fish didn't die but it's been about 3 months of them lying on their side, sometimes they even lie on top of one another. lost all colour and are black.
The leopard ctenapoma has also started being jerky and not breathing well. spend a lot of time hiding in corner of tank
Went back to hollywood and to animates, couldn't get any more info out of either. did a 2 week course of Furan-2 on their advice. no improvement. They have now recommended Trisul but the vet won't sell to us.
ANd finally, my pride and joy Henry, a gorgeus large snakeskin has just started showing his heckle bars and clamping his top fin and doing rapid jerky movments
I don't know what else to do, it;s obviously contagious and that's why we didn't split them up into quarantine tanks on the advice of the experts.
Any help guys would be awesome. It's been five months. We lost one of the discus (who first showed it) yesterday
