ok so my dad dumped 20 feeder goldfish water and all into my 125 without me there. the fish ate a few and I took the rest out. so awile after that my water stunk and got kinda dirty fast. all the other fish were doing ok but my jag was not. he was resting on the gravel a lot and became skittish. I thought it was a combination of my water being too hot for too long(82f) and the nasty sick goldfish. so I did a 50% WC then I added a little bit of aquarium salt and lowered temps to 76(too fast big mistake). now my fish have a minor case of ick so I put the temps back up but they are still moving up gradually cuz its cold in my house a lot. so at this point my Cuban looks a little stressed and my jag lays at the bottom most of the time and if he moves its because he got spooked by my presence. he has been running into heater/filter intakes and everything else he banged into the glass and splash so much water I thought he was gonna die. his eyes have some ick on them so I would assume that's whats bothering him. this is pissing me off I HATE when stupid things like this go wrong. SIDENOTE: this happened over a few days time not all at once it just progressed. WHAT SHOULD I DO???
