Hi all -I've 4 small loaches in my quarentene (20 liter aprox)tank and was to put them in my main tank this week, one of them is in trouble though .
I spotted it going madly in tight circles this morning and didn't think any thing of it, i've just got in from work and found it curled up and breathing heavily.
i've done a big water change and added an extra airstone...it's all i can think of right now .
fish seems ok otherwise -no wounds that I can see and colour seems ok
tanks small but ive been doing small(20 %ish) water changes every other day, temp normal (28 deg c)
the other fish are hiding which seems to be the norm saw them all yesterday though- so I dont know what they're doing
