I remmeber people saying the less the better, saying somethinga bout big amounts of chlorine/chloramine in tap water will kill them easy? How much % WC do you do for your channa? Specifically, channa gachuas?

If you are refilling the tank with a hose simply let it run for a few minutes before topping up. Any chlorine will be gassed off, chloramines are easily treated with a product like Aquasafe etc. Check these products carefully however, as very few deal with Chloramine properly, despite their claims.The main problem with all snakeheads as far as I am aware is that of a) intolerance of heavy metals (again a good water additive will neutralize those), b)they are intolerant of pH fluctuations and finally c) they do not like wild temperature fluctuations. Of course if the temp stabilises within a few hours that's fine, but not if it takes 10+ hours etc. It really depends on the size of your tank, how you fill-up and what water products you use. I think 20%, twice a week, at equidistant points would be a good start. Some put forth the argument that because they take in air at the surface water quality is not such a big deal, this is a perverse and intellectually non-sensical stance. Hope this helps.JESTERX626;712275;712275 said:I remmeber people saying the less the better, saying somethinga bout big amounts of chlorine/chloramine in tap water will kill them easy?

I have been told that they will tolerate water that would have most fish gasping. But i'm not going to put that to the test. Please do watch out for temp fluctuations when changing water though as this has killed channa in the past.
phen_dox will probably have no probs as he lives in a lovely hot place where his tap water is going to be pretty warm anyway? maybe?
Anyway I change 35% every week, I heat and treat the water before adding it to my tank eg. Fill bath to temperature (no probs with tank water temp fluctuations) then add "fresh start" and syphon down stairs into to tank.
