Yes they do come a bit after the light is out but since yesterday they are now venturing out a few at a time with the loaches. I may yet rearrange or get a smaller piece of driftwood as they still hide in the tunnel and under the filter but at least I can see where they are now. Will give it a month or so anyway, HFF will soon be giving me a key for all the visiting I've been doing lately .
The lighting is quite dim I think, it's a 7 watt clip on T5 that comes from the left side to the middle, the right side where the filter is gets less light. Also as I'm treating it as a low tech tank the lights only come in the afternoon till evening for 7 hours.
Those loaches are funny, extremely active. As evening set in they started going up and down in the current and almost putting their whole face out of the water. Then they would swim over to the other side and fluff around in the sand, flicking it around, and this morning they have worn a 2 cm dent in the corner. :lol:
