ouch, that is expensive!! not that i'm put of drastically mind you.....
we have just sold our marine tank so we've a kitty of a couple of hundred pounds with nothing in particular to spend it on
our substrate is black too, or certainly v dark browny colour
like the look of
similis and
guapore
purdy fishies!!
I also have a group of
C. similis on a black substrate. They look great too. The dark substrate makes their colors darken up nicely. Same with the
C. duplicareus. The
C. guapore are also very nice. I have almost bought a group of them several times and still would like a group. You really can not go wrong with any of those, but if I had to choose and after seeing them on the black substrate, I would go with the
C. duplicareus. I only have 5, so I bet a group of 15-20 would be quite a site
