Hello Can anyone help me with this I had 4 bala sharks 3 out of 4 are now dead the 3 had what I thought was fin rot so I moved them to an already setup 10 gallon to make it easier to treat them with "Mardel" the first 2 days of treatment went fine the 3rd day one fish was dead come morning with a red and white spot on its underside between its front fins and so there were two and then last night treatment day 4 the other 2 were dead with the same mark on there underside see attached picture for basic idea of location any ideas what it can be? They were about the same size as fish pictured
Here are my specs for the hell of it
