Ahh, So i went to my cousins last last night and we were all sitting around in his living room and I spotted a betta out of the corner of my eye.
I hadn't even noticed him before because he was sitting in a little jar almost behind a potted plant.
I picked him up to take a look at him. The jar was super small, less than half a gallon
Being all betta nosey now I immediatly let her know it was a too small.
I also noticed right away he had reeally bad fin rot, he was a crowntail but almost all of his rays were disintegrated with only a few still long. I asked her about water changes and she said it had been about 2 weeks and that the bamboo she had in there would filter out all the bad stuff.
Of course i said they should be done every day in that small of an environment, and I also pointed out the fin rot and told her it is probably from the water quality.
I have a feeling she isn't going to take my advice though
