After about 8 months plain sailing in my main tank I seem to have a problem, details of tank stocking and size are in my sig.
I noticed this week a female swordtail was spending a lot of time not moving at the top of the tank, I noticed yesterday that she was barely able to balance and basically being blown around by the flow in the tank at the bottom and not really self-righting. I took her out and had to euthanise. There were no outward signs at all on this fish.
I then inspected the rest of my fish and noticed a Hengel rasbora with what I can only describe as milky cloudy fins, not spotty at all but kind of streaks of cloudy white. He too was hanging out at the top and not moving much. I removed him and put him into a hospital tank. Woke up this morning and he was dead.
I've now done my weekly 25% water change and weekly water tests. Ammonia and Nitrite are both at zero and nitrates a fair bit higher than normal at about 40, a bit odd as it is normally round about the 10 mark.
I have now noticed a second Hengel Rasbora acting funny, hanging around on his own away from the shoal. He has a white bump at the end of his back on the top where it meets the tail fin. It is solid white about 3mm big, I would not say it looked like a grain of salt and it is the only one I can see on him. As this species is quite see-through I can also see some blood underneath the spot. I'm wondering if it is some sort of fungus or whether he has maybe been nipped.
One of my congo tetra also appears to have some white on his tail fin but again I would not say white spots. He is acting normally.
Can somebody please advise what to do as I am obviously keen for this not to spread to other inhabitants.
I will try and post photos this evening.
Thanks, Andy.
