dorsey, yeah we are prepared for problems both with growth and possible breeding, we have another tank to be set up soon for holding mothers / eggs / fry, whatever occurs.
where did you get your moonlighting from?
also i'll ask you as your set up is almost identical (same tank but 240, same lighting ocean rocks etc) we have quite a bit of algae on the rocks, well not loads but a steady layer, its like a mixture of brown and bright green! is there anything we can do to get rid of it or prevent it? we just got 4 nerite snails and they have all cleared their own patch, took it back down to bright white rock infact! but you get the feeling it would take them about a year, now we are planning on making it 8 snails, adding 4 to the 4 we have now, as they aren't bad looking and do their job, but is there anything else we can do? we have a break of light for a few hours during the day aswel, light on 4 hours in the morning, then off 4 hours then on 4 hours in the afternoon, this is why i do want the moonlight like you said to see them at the times when the light would normally be off!
because the tanks at my girlfriends its going to be difficult putting a piece of paper on it to verify it, and awkward as its in her living room, they would all think im weird! so can't really be bothered to be honest!
its a shame about the leptisoma, the male in particular is stunning, pictures don't totally show how metallic blue it actually is. any ideas how much i should put the pair up for sale for? we bought loads together so don't know how much they was!
thanks for the good comments, i do pass them on to the other half, although its all my hard work! haha
cheers, Dave
You make me wish i put tangs in my roma 125 now,
