its not so much the temp its the fact that when cycling the tank the water gets fairly toxic and potentially lethal... i certainly dont advise cycling with a moray which produces a lot of waste and even some people dont liek using live animals at all.
personally black mollies aclimatised to marine water work great
the only reason i was thinking a moray would be because the waste output would be similiar to an octo as eels are dirtier than say a black molly or two. so the bacteria would get 'up to speed' just what i was thinking....
al the rock and stuff is already cured/cycled from a previously established tank so i guess ill wait for th sand then pop a few molies in there then go wih the eel. thank you for your advice !! i love tonmo.com
What I do to make sure a tank can handle the appropriate bioload, is to add some pure ammonia to the tank every day. For instance I have a 60g hex that is cycling ATM and coming along nicely, but before I put anything in it I have been putting a small splash of ammonia in (maybe 5ml worth) every 2 or 3 days, after the levels reach 0 0 again. When you can add a fairly large amount and see it hit 0 0 the next day, then you can be completely confident that you can handle a bioload much greater than you will put in it.
I did a fishless cycle on my 120g freshwater this way adding 5mL of ammonia until I got readings of 0 0, and I added approximately 35 fish the first day and have never had the levels go above 0 0 still to this day. Very cool (whereas putting fish through ammonia is very uncool)
The ammonia must have no surfactants. If you shake the bottle it should not foam whatsoever. I got some from walmart if that helps, i could check exact ingredient list and brand when I get home if that helps you.
