Hello everyone. I rescued Willie from Walmart about two weeks ago. At first I had him in a one gallon tank but I have upgraded to a two gallon tank (and am eventually hoping to get an even larger one). The tank has a bubble up filter, preset heater @78F (I have a thermometer...P.S. I do plan on getting a better heater when I have the money) and I treat his water with Jungle Start Right complete water conditioner (previously was treating w/Proper PH 7.0 until I learned this was not good for him). I was only feeding him Tetra freeze dried blood worms (which I know is not a healthy diet, but I couldn't get him to eat anything else) but I just got him to start eating Aqueon Betta pellets (I just had to split them in half after soaking them). umm lets see what else... I have been treating him with API Bettafix for the last 5 days because his fins looked kind of rough and his colors were pretty dull (& I must say he looks excellent now!)..... he is very active and seems very happy.. he flares at his reflection..etc etc.
The only problem seems to be this small lump on his rear side... just wondering if anyone could tell me what it is...if its serious...and what I can do for Willie. Thanks!
