15g tank problems

Shekoi

Trying to start up again
in my 15g i've had to remove one of the rams as the larger one is always chasing and stressing out the smaller one, she is now much happier swimming aorund my 40g.

since i removed her i have lost a rasbora and the, male ram has a red mark on his side? it isn't affecting him, sill feeding all fins up etc?

what could it be and how to treat it?

cheers shekoi
 
The bully ram may have simply turned on the rasbora out of boredom. As to the red mark, keep a close eye on it. Certain bacterial strains can do this. Antibiotics work well for these things *if it's a bacteria* and you have to have the right kind of antibiotic. Primafix may do it as well.
 
You should put the male ram in quarantine and perhaps treat it with some medication. It might be infectious, so it is best to move it into it's own tank and treat it until it is better.
