Im Worried About My Fish

[CrayZeeSpit@hotmail.com]

Ive had tank for a while now without any problems but last night a did a water change, didnt do anything different then i normally do and tonight most of my fish are breathing rapidly and my plecos are releasing air bubbles then rushing to the top of the tank and back down. Whats wrong and how do I fix it???

How long has your tank been running and what size is it?

Which fish do you keep?

What are your water stats\?

What filters do you have?

I have 2 3 inch oscars, 2 feather fin catfish, 3 plecos, and somes snails in a 40 gallon

common plecs always go up for air approx once every 10 mins - you should see them releasing the bubbles then going up for more air

how long have you had the tank set up and how long have you had the plecs

your tank is overstocked, do you know your water stats?
1 oscar alone needs at least a 55 gallon tank
do you do a gravel vac with the water changes?
how long has the tank been running?

do you add dechlorinator to the water ?
how long was the tank set up before you added fish ?

what are the water stats

ammonia,nitrites,nitrates ph and temp
