Betta With Chronically Torn Fins

Hi. I've had a Betta for almost 2 years now in a Fluval 2.5 gallon (which I realize is on the small side). It has a clay cave with no sharp edges and some Anubias tied to it. Temp 78 degrees. Parameters 0/0/5. Weekly 30% water changes. His fins became town shortly after we got him. I removed another cave with sharp edges but his fins remain torn (although clean with no signs of finrot). The only thing in the tank that I think may shred his fins are the Anubias roots, which have become pretty robust. I was thinking of removing the Anubias and replacing it with Anacharis or some other plant that is soft and won't develop large roots. Any thoughts before I do this?

Thanks,
Vasyat

 

Can we see some pictures of him and the tank? I've never heard of fins being ripped by anubias roots before. I have an anubias with a big root system in my betta tank that's floating and I've never had a problem with it.

Here are some pics. Thanks!

 

It's possible. My anubias roots poke out a lot. I could see them maybe catching on long fins.

You might try putting your hand in a clean pantyhose or knee-high, splaying your fingers, and gently running your hand over everything in the tank. If something can snag the nylon then it can probably snag a betta fin.

 

I'd check the Betta log. lots of comments about that issue in reviews at amazon. people had to sand down the inside. I did not buy one for that very reason.

 

It's probably that log that you have in there. I took out all my betta's caves in 2 tanks that I'm finding torn fins. They're almost always the culprit. If you run a pantyhose through it and around it I'm sure you'll find some snags. I sanded my betta caves down and it still tears their tails so for now it's only plants in there.
