Ive only just noticed this after posting my last thread for help.
Sorry for the spam :( but...
...Is this Fin Rot?
I've speculated some other problems that might be happening to him as well in my last thread.
I need urgent answers to the following questions please:
Chlorine prob---> should I move it to a 10 gallon aquarium that's already housing a goldfish and other unknown tropical fish(small size)? (It's got a filter, cycle, and the temperature's fine.)
Epsom salt--> should I get some from my school laboratory (Magnesium Sulfate) ? (is it going to work/ be safe for my fish?)
I'm afraid it'll die :(
