This is very cool indeed, I have a group of 9 bluestreaks in a 40 gallon tank with a pair of seahorses and one small ocellaris clownfish. They breed constantly ( I see males holding) but I have never seen a larvae and have made no attempt to capture any yet. I need to make some changes to the set up like modify the overflow or just shut off the supply pump at lights out. It's on my "to do" list
Since I can't tell one fish from another I have no idea what the frequency of spawning is, if the pairs are manogomous or what. They are a group (schooling) so I don't
think they are pair bonded but I really can't say for sure. I don't even know how many of each sex there are.
Please post at the next spawn so I can get a better idea of the frequency. Maybe I can find some time to try working with these guys, keep the log going and I will try to add to it if I get anywhere.
