Hi, Autumnsky.
This is an accident post. I was trying to post this message with a picture but it didn't work and I thought I deleted this one. There is another post with the same name and a picture of my fish. Maybe that will help.
I have thought about her scraping herself on a decoration or getting stuck. I'm not sure how to prevent that in the future. There are two orandas and one ryukin. I've been watching them since I put them together almost 8-10 months ago and they seem to have been doing fine. They have been getting along very well. I've been using a liquid formula to keep the water at proper pH level and stuff. I have a 20 g. tank, hoping to get a bigger one soon, and a 10 g. med-tank. The other fish are 3" ,tail to head, and under. Two orandas, one ryukin, and one pleco (properly treated then put in about two weeks ago). I change the water monthly but weekly clean out the floor of the tank using a siphon then refill the tank with conditioned water.
