I have an 8 inch Alligator Gar in a 125 gallon tank and it moves around fine, has great color, eats fine but it has a round cyste like thing on its tail. it is pale orange reddish. it has had it for awhile even after i treated it in a quarantine tank with parasite meds and also bacterial/fungul. Im worried it may be something pretty bad.
also it is in with a RTC, green sunfish, and Tiger shovelnose cat
