Thank you so much for the answers and suggestions. A friend will help with re-homing the plecos and the loaches (I have 2 of them too...damn lady in the shop).
In the meantime, sorry to ask again but I am not sure what else to do. I did 3 good water changes and levels seem to be OK now (Nitrate is definitely under 20 and Nitrit zero, but I am still with the strip test as the local shop doesn't have a better one till next week). I decided to keep doing daily 10% water changes just to keep good water quality until I manage to give away the other fishes.
However, the corys are still behaving really strangely, although they left the water surface. 2 slept the whole day (and look like they are breathing heavily), one looks literally like a 'zombie' fish, spending all day swimming from up to down really slowly and heavily, yes lost and not eating anything, another one attempted to eat but still looks very strange.
My question is: could the suspected ammonia peak/or the use of the PhAcid have damaged them permanently (neurological damage)?
could they have some sort of infection (but I inspected them quite well and apart from looking increasingly thinner and breathing heavily, they look perfect)?
Is there anything else I could try to help them?
Thank you so much!!
