This isn't unlikely at all, except for the fact that it had to jump back the way it came, which does seem a bit weird. How high was the water level compared to this 2cm space?

It sounds from your description that the fins are physically ripped apart; these other "chemical" types of things, if they are so bad as to cause a problem, would be likely to cause fins to rot away over time, as if the fish has fin and tail rot, don't you think? Bettas fins always grow back out by themselves, don't do anything different than what you usually do with the bettas. -Derek I have a betta alone in an Eclipse and had the same overnight shredding. There is gravel and the intake for the eclipse, but no plants or other objects. It always mystified me as it happens whenever I get a betta. I have never seen the betta rub on the gravel..... |

Sensible idea, though. The water was high enough for an easy jump. The divider is plastic canvas to the top of the tank, and the glass cover almost against the HOB filter intake. If I put it flush, it rattles. I thought the filter intake was in the way enough to prevent such a mishap. Obviously not. :-( I have made any further jumping impossible with more canvas. The damage does look physical, and not at all like fin or tail rot. That's why I was so shocked by the suddenness of it. With toxic water, I would expect to see white edges, fairly even damage (the dorsals are nearly perfect on both fish), and behavioral signs of stress. Good to know that I can do my usual clean water thing even for fins this damaged. -- Elaine T __ http://eethomp.com/fish.html '__ rec.aquaria.* FAQ http://faq.thekrib.com |

My tap water is more alkaline then my tank water so if I'm not careful and change too much water (50%) the pH levels fluctuate more then the .2 safe range. That's when I notice shredding on my old betta. I actually haven't heard anyone verify that pH fluctuations can cause shredded fins so I can't say for sure if this is true, but I have seen it a few times now and it's consistant with pH fluctuations. That is interesting, I was playing with ph up when that happened to my male betta over a decade ago, it's possible as I see it that ph fluctuations can cause this. But I must say - in elaine's case I think it's just very clever and always surprising bettas, my empty bet is that one of her bettas jumped the divider, fought with the other one and jumped back or something similar. I know they can really jump (bettas) as every once in a while when I had my betta (and female betta at times) it would jump straight up and ram into my aquarium glass cover with a lot of force and a big banging sound, I think only the female did this though and I think that's what eventually killed her by putting her into terminal shock. Good luck, and later! Maybe someone can verify or discount this theory for me. I'd like to know. I'd like to know too. Thanks, christie Really? I did big water changes Friday and Sunday since I've been battling algae growing on the java moss. I wanted to lower phosphates. Seems like Sunday to Wednesday is kind of a long gap but that makes more sense than anything else I've come up with. My tap water is alkaline and variable - I've tested it as high as pH 8. The pH of the betta tank usually stays fairly close because there's no gravel to trap anything but I didn't test this time. Does the shredding you take a few days after the pH change and then happen literally overnight? Happily, the little guys are looking fine in every other way. -- Elaine T __ http://eethomp.com/fish.html '__ rec.aquaria.* FAQ http://faq.thekrib.com |

It's very possible for male Bettas to hop from side to side for fight
and then flip back over into his own side. This is main reason I don't keep divided male Betta tanks. I keep them in either 1g's, 2 1/2g's, or 3g's by themsleves. The females I keep in my 75g with my Angelfish. I've seen Bettas jump through the smallest of openings. It's amazing how good their aim is when flopping out of the water, through a hole or wriggling through a space to have either a fight or to spawn, and then find their way back again. |

I won't believe for one second that cyanobacteria or ammonia or pH
variations or anything else similar will cause a bettas fins to tatter overnight. It sounds from your description that the fins are physically ripped apart; these other "chemical" types of things, if they are so bad as to cause a problem, would be likely to cause fins to rot away over time, as if the fish has fin and tail rot, don't you think? Cyanobacteria is caused by high ammonia and low nitrate. By the time you have a bynch of it it's used the ammonia so it'll test 0. But with ammonia in the tank anyprotozoal disease can take over very quickly. It's easyt to miss the beginnings of this and they can seeeminly overnight go from what looked like a perfect fish to a tattered mess. Acriflavine cures this 99% of the time. Anything similar should work.

And nitrates are low because of the clumps of java moss and floating watersprite in the tank. Funny you should post this today. I was actually thinking of adding copper, formalin/malachite, or permanganate this morning because I just wasn't quite convinced it was a fight. I almost bought acriflavine at the pet store today and decided against it because I didn't want to kill all the nitrifying bacteria in the tank. I'll go with formalin/malachite since it won't trash my filter, I have it around, and it works for most protozoans. Hopefully it won't inhibit fin regrowth if it was a fight.

Fine the night before, and absolutely shredded by morning does sound like one hopped over divider. Don't dismiss that so lightly. It is *very* possible and the main reason i do NOT divide male Betta tanks, as well have lids on any of them that are next to one another. These fish are very capable at aiming their bodies through a very small place...and getting back. |
