good morning. thanks for reply. it's 4:30AM and I'm still at work. I can't wait to go home at 6:30AM to see how my frys are doing...
I heard that other breeders' young male fail many times before he actually release real frys. From my first two spawns, I think I know why. It's the water!
This is what happened.
My second pair of WC macs was moved into a 20gal, and I put in one largest male from my 6 CB males tank to make a trio.
Last Friday the 9th, the trio spawned. The weird thing was that both WC and CB males were holding. But the females keep attacking the CB male to protect the WC male, obviously that she choose to mate with the WC male, but the CB male joined them anyway. They had a successful threesome.
This spawn failed. After the 2 males holding for two days, they both swallowed the eggs.
So the qestion is why the first male successfully brood and released fry while the other two males did not.
I didn't do any water testing, but I know it's the water.
The male that released fry, spawned in a 30 gal tank, which equiped with a trickle-filter that hold 10 gal of water and 5 gal of bio-ball and bio rings that packed with huge colony of benificial bacterias. This tank has the very very clean water. No ammonia, nitrate or nitrite.
While the 20gal that the other two males spawned in only has two small sponge filter.
One other thing that I gain from the first spawn was that the female will be ready to mate a gain in a week. This is the time she start to bother the male, what was why she was removed.
Also, the male did not hold a mouthfull of eggs, there was an air bubble in his mouth, and she shuffle the egss once in a while to make sure they all come in contact with oxigen.
Oh, one more thing. The egg will hatch in his mouth in about a week. Day one to day 7, when he shuffle the egg in his jaw, I could see white thing is his jaw. But after day 7, the eggs hatched, and the fry are in darker color than the eggs.
The eggs hatched and developed in his jaw. The released frys are quite large. They are about the same size as 1 week onle betta splendens.
The thing that amazed me was that how a small male with small jaw can hold 18 frys with that size. I think the frys are small in his jaw, but immediate grow big once released into the water.
I will be off Wed and Thur, I will post some pic and or some videos.
