I have a 29 gallon tank with 4 ghost cat fish, 3 neon tetras, 1 bristlenose catfish, and 1 male betta. Originally I had my half moon betta in my 29 gallon tank and the edges of his fins kept tearing, someone said that half moons tails tend to rip easily, so the next time I cleaned my tanks I moved my half moon to one of my 2 gallon tanks (his tail looks better) and moved my veil tail into the 29 gallon. His tail started ripping, it will heal most of the way and then another big tear will appear. I have 1 plastic plant in the tank that I have used with several other bettas and never had a problem (and both of my 2 gallon tanks have plastic plants without any fins ripping). All of the other plants in the 29 gallon tank are silk plants. What could be causing his tail to rip, at this point he is started to look more like a crown tail then a veil tail at the edges of his tail?? Any suggestions would be helpful.
Here is a picture of my 29 gallon tank, all of the plants except the purple one in the right corner have been removed and replaced with silk plants
