A Bangaii Report

[David M]

Frank will like this, I have some young bangers born last April so call them 10 months old. I have been pulling pairs from the group (10) over the past couple months. One of the pairs shares a small bare cube with a young pair of clowns and a pair of blue assessors. Crowded bare tank, lots of activity around it, daily siphoning, just a holding situation. Last night I recoverd about a dozen eggs from the male. Just goes to show that if fish wanna breed conditions do not need to be optimal

Interesting. How long was the male holding the egg ball before you collected it? My male won't hold and I've been suspecting the crowded conditions and 2nd cardinalfish species to be responsible.

I never noticed them before last night, I'm assuming they were quite fresh. I figured there was no way he was going to hold them long, his first effort on top of everything else, so I pulled them presumably on "day one".

Hi David, when you say you have been pulling pairs out of a 10month old group of fish, are this fish all from the same parents/batch? have you ever noticed or heard of issues mating fish from the same batch? reduced gene pool. Also, have you found that the % of survivers is greater when the eggs are removed from the male before they have hatched compared to fish that are recovered once hatched? What do you feel the benefits are with removing the eggs for the male instead of waiting till they hatch, apart from increased breeding & left fasting period for the male.
Sorry about all the questions.

Also, if they are from the same batch do you simply allow them to mature as a group until they pair up?

How big are 10 month old Bangaii? I ask b/c I bought what was sold as a young pair (i.e. they weren't trying to kill each other, LOL) a couple of months ago. This evening, I swear the male is either holding or has the mumps! I really didn't think they were big enough to spawn. I have no idea how old they are, but they are CB from Inland. They're in my 125 with a pair of spawning GSM, maybe it's "fishy-see, fishy-do"!

DS- The general consensus is that you will not see any problems inbreeding or linebreeding fish for at least several generations. Sure, in the long run it's probably not optimal but captive breeding is in it's infancy and we are pretty far off from from experiencing complications. Harvesting eggs from holding males may be the one and only thing that makes breeding bangers even remotely profitable. Search for threads by Coral Dynamics, there is a video you just have see.

Yes you simply allow them to mature and the pair will be obvious. If you don't remove them rival males will be killed. Of the ten I started with I pulled 5 pairs, that's as good as it gets

Cat- they are barely 1" body disc, I was shocked they could spawn but Frank has been saying this all alopng.

David, that's about the size of mine. I've seen the breeding pairs they have at Inland and some of those are HUGE so I assumed mine were a long way from spawning. It'll be interesting to see how he does this first time. As of this morning, he's still holding.

From experiance as what age (in months) will they start to pair up? if its the video i am thinking of, its the one with the eggs in the tumberler that begin to hatch. I have rasied a few batchs & have always sold them before they pair up fearing of fighting/in-breeding. I currently have a batch of 7 at about 1mth old that I will not keep & see if they pair up. Over in the UK there have been lots of chat between breeders about swapping fish to eliminate the risk of inbreeding, but even with a country as small a england, its still to far to warrent meeting up. How do egg tumblers work? how do they get constant water flow to ensure the water doesnt go off, stay opt temp, etc.
