I don’t think the inanga would like much more current than that, although they do seem to spend a little time in the inflow, trying to get further upstream?
I'm liking the sand although it isn’t really the torrent fish or the inanga's natural/normal environ.
I have taken much of the leaf litter out and only left in the bugger bits. They do look good, and you never know where in the tank they are going to be.
At the moment the are mostly eating daphnia, waterboatmen, backswimmers, mozzie larvae and small amounts of beef (need to get some heart). oh and the inanga have taken a liking to the shrimps :an!gry
