yeah, once after the water change, he is fine... its only when i drain the tank... and afterwards he just goes back to sand sifting... but once i start doing water changes. like right after i drain about 3 inches of water out of my 300 he goes nuts. and then gets my ID shark nuts... then a chain reaction happens (half the time)... but i know for a fact the african arowana is the culprit.
I was going to suggest that the new water might be irritating the Afro but that does not seem to be the case.I'm guessing that the draining startles it.
Your arowana is stressing because he thinks the water is drying up. I dont know what to do other than to give it time. Hiw long has this been going on for?
When I drain tanks, I have new water coming in at the same rate it drains. I just let them run that way for awhile after I am done vacuuming. Yes I waste a lot of water. We use free chlorine here, so it isn't much of an issue. Maybe try that?
Roger I can't do that as I have chlorine in my water. I do water changes with the lights on. It's highly annoying cause the chain reaction isn't exactly gentle on the tank or the fish. They all now have injuries. And this happens almost every time
