I just bought my 4" arowana from a lfs and all of em had rough fins but this one is getting worse! i figured it was cause they where young and theyd fill in. but today i got home and hes sitting on the bottom with bad looking fins. I currently have it in a 10 gallon with piranha in it before but i did a 50% water change after removing pirannha and before adding arowana, there is currently a plecostumes and some feeder guppies in there. im getting a 55 gallon in 2 weeks and then in a year a 180 gallon. ill include a pic, is this indeed fin rot, tell me his fins will come back to full beauty, also what should i do? i noticed the temp was at 74 degrees so i pumped it up i read they need 76-82.
p.s. HELP!
