Topaz with lumpy belly and open vent
Posted: Wed Jul 04, 2018 12:44 pm
Hi
Had 3 topaz puffers now for around 4 months in a 200 litre tank. Feeding well and very active.
Nitrite/ammonia at zero, Ph around 8, Nitrate is slightly high around 25ppm due to local tap water. Temp 27 degrees C.
50% waterchanges done very 10 days.
Using FX6 external canister plus large internal air powered foam filter.
Feeding mainly earthworms, snails, large krill and cockles plus occasional bloodworm, large king prawns and mussels.
After a good feed Monday I noticed the largest of the group has lumps around his rear underside either side of his vent plus the vent is now a large hole (pen diameter) so very concerned. I have added Marine salt at 5g/gallon to raise the salinity slightly but only by 0.02 at present. Previoulsy were in freshwater.
As of today he still looks the same and is still active bit I am serioulsy concerned about these lumps and open vent. The other two are totally normal shape and the vents look normal (not a gaping hole).
Any advise welcomed.
Thanks
Chris
