Hope you don't mind me hunting you out...you always give great advice when it comes to fish!
I'm not having a good time with my pets at the moment. First my dog had a meltdown and now my two goldfish seem to be suffering with swim bladder - one floating at the top of the tank or sitting on the gravel, the other floating virtually vertically, head down.
I bought some swim bladder treatment (Interpret), which I've dosed the tank with about four times, every four days. Together with this I've added some aquarium salt.
Whenever I do (partial) water changes, I add drops of ammo lock and stress zyme to the new water. (I've been doing small water changes with each dose of swim bladder treatment as I need to add more water with the treatment each time).
One fish seems to be doing much better, but now the other (who used to be less affected) seems worse and is vertical a lot of the time. It seems to be a real effort for him to stay straight
I've tried feeding them grapes but that hasn't helped - well it might have helped a bit but they're still not great.
One thing I don't have is any water testing kit. I'm starting to think this might be essential, am I right? I'm really not sure about a) what to get and b) what to do
I'd be so grateful for any advice. I'm very fond of them and want them to get better...
Thanks
