Red face New fish, minor rot


I just (as in less then an hour ago) got (rescued?) a betta from Wal-Mart. Poor guy was in about a cup and a half of water for god knows how long.

He appears to have a minor amount of fin rot and 1 spilt in his back fin. I was wondering if I should do anything to help him get healthy.

He has brand new, clean and dechlorinated water. A washed everything (tank, plants, filters, decoration, heater, gravel) in treated water before putting it in the tank. His tank is currently at 79 degrees and the heater is set to keep it at +/- 78 degrees. We set his sad cup in the water to temper it to the water temp of his new 5 gallon tank before letting him free in the tank to explore.

Should I do something to help the rot heal or just let him enjoy the new large clean tank and hope that fixes the problem?

Thanks for the help!

What I have been doing with a halfmoon that I bought from Petland is changing his water every second day. As long as you keep the water extremely clean his fin rot should clear up on it's own. My fish is finally starting to have new growth. It's been a long battle to get him healthy.

^That is fine. Clean water is the best medicine.. If it seems more severe you may want to treat with aquarium salt.. If you can adjust the heater, turn the temperature up to 80F (monitor with a thermometer) because this will also help kill off the fin rot.
Also since your tank is not cycled, you should probably be doing two 50% changes a week. You may want to do more until he is fully healed. Heads up, your filter probably says something like "change cartridge every month" Don't do this.. your cartridge will grow bacteria that eat away ammonia over time, and changing it will just get rid of the bacteria.
