When my rays came in, they were showing ammonia poisoning stress, and the female didn't make it- I keep a school of tin foils, and 5 datnoids in my tank as well. I run 3 Ac110's and an eheim pro 2 on this tank.Tor-Eriik;5046927; said:I change 50% every 4 days, plenty for me.. Watch the nitrate readings, thats what you change water for mainly, when they are between 25-50, theres a waterchange that should be done. 50% every day to me seems like alot of stress to the fish and unnessesary work. I have 2x180g with 4 rays in both. 1 is filtered over 2xfx5 and the second over eheim 2080 and 50l background filter.
I normally do 50% water changes everyday because I dont want to take any chances with them in a 125. Once they move to the 240 I am not going to do water changes that often.
The rays don't stress in my tank- not sure why they would. They are rather happy when they see me as I am known as "FOOD!!!!!!! "
