We have a 125l Juwel Rio tank with 2 discus, 5 neon tetras, 5 pristella tetras and a snowball pleco.
We are currently treating for white spot and have noticed that one of our discus fish has stopped eating and has white stringy faeces, it also looks down in itself and is not very active. The other discus has started to bully it and nips it quite agressivley. It also seems that whenever there is food around he nips more so that it wont eat at all. (Food passes it and it wont even acknowledge it).
I will add a couple of pics, can anyone tell me what this looks/sounds like please?
