Urgent!!!!!!!! Need help!
hey guys! Okay so I haven't had a betta in a few months (Ish died tragically when a long hair of my mother's fell into the tank and wrapped around his fins and body, suffocating him) but I do have two large goldfish, each 2" long, and a tetra 1" long, and two cleaner snails. The fish have been sitting at the bottom for the last few days, so I checked online and it said there might be an ammonia spike. Immediately I changed out the water by 50%, changed out the filter, and will not be feeding them tomorrow. I don't have an ammonia test kit. Goldfish, like bettas, will sometimes take air manually from the top of the tank, dipping above water. Resting them gently on my hand, I took Sosuke and Ponyo (the goldies) up to the top and let them rest, tipping their mouths above water. They are both sluggish, Sosuke more so than Ponyo. Baby, the tetra, is fine since the watr change and is zipping around the tank. Both snails seem fine.
[B]What should I do??[B] I'm so scared for them, what can I do to help? Should I get more cleaner fish? Should I move the fish to a clean tank while I clean out the old one (i don't think i should do that, it might kill them)? Please please help me!
