I have a danio who is, for lack of a better word, going crazy. She's whirling, spinning, crashing into things, and when she's still she's lying in the plants. I can't catch her - I've been trying for hours now. She's so fast and because of her behaviour, incredibly difficult to predict where she's going to go. What is wrong with her? It's like brain damage or something. There is nothing right about her behaviour.
We've had recent troubles in the tank. A sharp increase in nitrates lead to some sort of fungal/bacterial outbreak. I lost 1 danio to a huge fuzzy white ulcer on its back, a platy got a fuzzy eye which has recovered now. No other poorly fish, treating with melafix. Got one day left of the 7 day treatment.
Tested the water, ph is somewhat lower than usual at about 7 (usually 7.6-7.8), ammonia 0, nitrites 0, nitrates <20. (They had spiked to 80 last week).
Tank is a 66g tall, heavily planted, with 11 danios, 7 penguin tetras, 6 platys (plus fry), 2 opaline gouramis, 2 gold gouramis, 2 BN plecos, and an assortment of snails. It's been up and running for months now and no new additions in about 3 months.
Please, can anyone shed some light on this? If I could catch her I'd get the clove oil out and put her out of her misery, but is it contagious!?
