I was thinking of getting another one as well but have no idea what the sex of the one I have is
males have a much longer dorsal fin..You can have a male and a female or two females in a tank together, but two males will fight... but it's hard to tell when they are young
Here's a good photo to show the fin difference in male & female...
The top one with a spike frontal fin is the male....squared off fin is female.
(That's according to liveaquaria.com)
Thanks everyone. I really like the arch and feel like it adds a nice touch to the display.
One question Greg, have you glued all your frags to get them to stay in place? (especially the frags on the arch)
Yes, I make a small ball with JB WaterWeld. Then add some super glue gel to the top and bottom of the ball. Dry thy frag base, then push the base into the super glue. Then push the entire thing in place where I want it. This way the super glue and water weld both work to bond the frag in place.
