I got a betta fish on February 14. He had black tips to his fins that are still there...the fins look normal, except for the tips. I can't tell if this is normal coloring or a diesease. I think his fins are getting shorter...maybe...but that might be my paranoia at losing him.
He is in a one gallon freshwater tank (don't have the space to get a bigger one). It's been set up since February 14. Only he is in the tank. There are no live plants in the tank. The temperature is 74-78 depending on the time of day. No filter, no heater in the tank just a lamp to warm him in case of random coldness...since I live in Florida that's unlikely. He doesn't get natural sunlight. I changed his water last Wednesday, haven't changed it since because I started treating him with Betafix. I feed him flakes twice a day because he refuses pellets (picky little darling) and a bloodworm every night. I turn his light on and off depending on the warmth of the water..but he has light cause the other lights are on most of the day. His pH is a little high...about 7.8-8...I need some help on how to get that down. Everything else is completely normal. I'm using test strips.
So...is he sick or is this probably natural coloring? I've been treating him but now I'm doubting my diagnosis because it isn't getting smaller that I can notice. And I don't want to keep dosing him because he is acting funny now...swimming near the bottom (not like swim bladder, just swimming at the bottom), flaring at me randomly...yeah...so can someone help?
