So recently my gf and i started a betta sorority. All was going pretty well, some fin tearing from hiarchy fletching but besides that the girls got along. Tonight after we returned home from a dinner with friends, i noticed i saw no bettas in the tank, even more worrysome, the filters tubing had fallen apart, the plastic part with the meshed intake had somehow become dislodged and sunk to the bottom, leaving a open tube intaking water. I quickly unplugged everything. Two girls slid out the intake, with some minor scale damage on the top of their heads. I took out the filter and dumped the contents back in the tank. Two more girls swam out. Some moderate fin and scale damage. And two girls sunk, very much dead. This is very hard on us, and after burying those two girls i have a few questions.
How the hell did the filters protective tubing get dislodged? Its was fine when we woke up this morning and randomly fell apart during the day. Easy repair, i just stick it back up there, but i dont want this happening again. It was a tetra whisper 10-30.
Two, i want the girls to recover. Should i take the four of them out and leave them in cups with fin repair and stress coat stuff? I only have a single one gallon hospital tank.
Three, althought they were doing alright before this accident. There was a decent bit of bickering. Almost every other morning i would wake up to see someone missing more of a fin or a tail. When should i remove a fish due to fin damage? One of the girls was missing a good 30% of her tail due to fighting. A note on fighting, i never witness anyone getting hounded, that stopped after the first 24 hours. There might be flaring and some lunging but no one ever chases anyone around the tank attacking them anymore. Sometimes they even do something that resembles schooling, with 6 girls all in the same corner of the tank, even brushing against each other with no signs of aggression. They also dont fight over food either.
Anyways. We need some help.
