okay i noticed that BB (blackbeard) looks like he might have fin rot today. i was transferring from the 3 gallon to the 10 gallon divided tank. now the old tank 3 gallon i had done a rescaping off last week and then noticed an algae spike (major) last night and then noticed today that the temp was way higher. i could feel it. well i was going to transfer him anyway and just decided to do it today because i did not want to boil him with heater being malfuctioning. and realized that the gravel from the rescape might be the problem from the algae growth.... it was outside in a container and i rinsed it, but apparently not well enought.
i saw on his fin on his tail is an area that is white and almost looks burned

? he always likes to sit beside the filter and heater..always liked that spot. he has been listless and sitts at surface now. (he has always been well.....a little persnickady..to say that least...he has a major attitude..always has) but i have never had to treat for this before. i have had him over a year and no problems...... so i know my last experience with medications was bad, bad, bad, bad ...........did i say bad

? that was with a community tank and
ICH...... until i learned about salt treatment.
so i come to my fishlorians............what to do


he is in a 10 gallon cycled tank. water is clean, clean, clean. i did add a tiny bit of aquarium salt but that is it......
