Hi there
I would ask questions like...How old is the pair of GSMs..or if unsure, how old has the pair been with you.
Constant light cycle?
How long have they been a "bonded pair"?
Are they tank-raised/captive-bred or wild-caught specimens?
I have raised and am still raising GSMs at this time. They are rather tough to start with if you are new to raising clownfish because the fry/larvae is very small. In contrast, larvae from Ocellaris clowns are almost 1/2 to 2/3 times as big.
If you can give a detailed description on tank, inhabitants, foods given, water temp...SG...etc, I can maybe hypothesize or give better suggestions.
Best,
Ilham
P.S. Doni, I love your new tank. I'm sorry about your other fishes
I have just heard Martin Moe breeding those yellow-headed gobies from the Caribbean. He has a nice thread in 'RC'. I'm glad a couple of them are going to you.
