I noticed the other day some swelling near my senegalus anus. Some reddening but not really too bad. I was thinking to treat with pimafix what do you guys think? Shes about 3 years old but is only 6.5" in length, she is still eating well and acting normal. 38 gallon, 0 ammonia, 0 nitrite, 7.2 ph, 25 nitrate. 82 degrees. I actualy first noticed this after treating the tank with praziquantel mainly as a preventative.
