Can anyone advise me?

I have a tank with loads of Guppy Fry. Two days ago I cleaned the tank and the first day they were all at the top huddled in the corner, during the day some of them came down in the tank. This morning they are still at the top of the tank, not huddled though. The temperature is fine and the filter is working okay. Any suggestions? I'm worried in case I loose them.

They got clamp fin.Chenge water and add salt.and some pottasium permaganate(if you don't know how much then do not put) or malachite green.Thoses that are better/stronger will survive

What is the ammonia, nitrite, nitrate and pH?

How much of the water did you clean? Did you empty the whole tank out?.....And about the melanchite green....you can buy a bottle called quick cure that contains this and the direstions are very easy to follow

Keep us posted and I'm sorry for your losses
