#fin biting

I did find the culprit (which was a decoration that had broken and gotten sharp), so the past few weeks have been spent keeping a close eye on Firecracker and upping water changes to make sure he doesn't get infected. Bottom two pics are from yesterday - the middle of his tail already seems to be growing back!

Okay fin rot or tail biting? im getting mixed signals from googling. Im worried. I ordered fin rot meds just in case.

He was absolutely fine yesterday, I have no idea how he tore it up so much in one night. I added some new plants and root tabs to the tank yesterday, but the only conceivably pointy thing in there is the driftwood which has been there the whole time (and I can't exactly take it out). Maybe he's fin biting... Idk, it's water change day today anyways so I'll just keep an eye on him for now.

The bettas all got more plants today, Ceviches tank is so full, I love it! Yuki and Tekkin could use some more especially Tekkin, but for now they look good. Yukis looks like a faerie wonderland lol . . (Ceviches tank is only half full because he's a chronic fin biter and it reduces the strain on his fins, luckily he's on the up and hasn't had an issue in a couple weeks)

For any one who is dealing with fin damage…here’s a 2 month before and after comparison of Red Guy. I didn’t do anything other than weekly 30% water changes and stable 78-80 temp.

Cabaret started Fin biting TT~TT I know how it started, and I know it was my fault... He started about 6 nights ago, I did a water change and forgot to put the sponge I use to soften the flow back onto the filter outlet. When I first realized, he had taken off about half of his tail's length overnight. I fixed the flow problem and he seemed quite happy - his colours were vibrant, he was swimming through and around his plants and hide (I didn't do a scape update when I put that in...oops...), he was dashing around the open top and he was displaying his - albeit torn to oblivion in the tail - fins nice and wide. I thought "Yes, crisis averted!" ...I thought wrong it seems... Although not easily noticeable, his tail apears to be growing shorter each day... which is such a pitty because there was such nice blue in the regrowth (my camera and the lighting don't show it well, hence the 3rd photo) I don't know if it's paranoia or if it really is getting shorter though... will he stop, or is this going to become an addiction of his? "Less tail = more speed, can I go faster?" Sort of a thing... Sorry that I haven't updated in a while... and yes, I know, I have an algae problem in the moss and on the val and that his water is low today (the evaporation rate here is weird...I never noticed it be this bad at my old house) but what looks like dirty glass is the lid, just saying... Once I have rearranged my little flat, I'm getting given a bigger tank for my tetra shoal and Cabaret will be getting their old one (roughly 7 gal instead of roughly 3 gal) although, I'm contemplating setting both the new tank and the 7 gal up as [more properly] planted tanks while their future residents are still in their current tanks - the 2ft because Black Neon tetra look good with plants, and the 7gal because a) I like plants, b) fishnets here looks good with black and green, and c) I kinda want to establish a shrimp colony to deal with algea, but Glutton Butt here tries to eat anything that so much as drifts slightly as the water shifts (even the duckweed perished before it could take hold) and they'd need somewhere - lots of somewheres - to hide, alternatively I could get a few otos, but they still need somewhere to hide. Also, all my plants in this tank have babies already and I've only had them for 3 weeks (excluding the moss, that's like 2years old and been through both tanks, I've pulled enough from that to fill a bathtub probably...)

Thank you to everyone who gave me some advice for Fishsticks's fin-biting. I checked and Fishsticks doesn't seem to have fin rot (thankfully). My water parameters look good, and I did a water change and rearrange of his tank. I also added some anacharis for him to rest on. Hopefully he'll stop biting. Other than the fin biting, Fishsticks seems to be doing ok. He's eating well, moving around, responding to stuff he sees, etc.

look at that fin growth!!
