Bangai’s bred in my tank!

It's so interesting how they're "easy" in a sense compared to other fish that need crazy specific copepods or other invertebrate diets at different stages, but still require live feeding. I've heard of people finding small ones in their sumps that have survived off of junk going over the overflow.

Agreed. They took to live brine easily. At the same time they are fully developed when they come out of the male’s mouth. Don’t have to worry about hatching or larval stages let alone microscopic diets.

Well,
Week 9.5 update. Some changes and a bit of bad news. I was able to switch them over to a 20g long tank yesterday. A big thank you to JVU for letting me borrow the tank.

The bad news is this morning I found two had passed away. The rest are all active and eating. I am not sure if they died from the stress or the "sudden fright syndrome" I read about online. From the information I gathered the "sudden fright syndrome" tends to happen within the first few weeks. I have been supplementing their diet with selcon and vitamin supplements.

I am still on the fence about their filtration. They still seem to small to avoid being sucked into the grate of the HOB filter. Fow now I continue to use the sponge filter with an air pump. I still can't get them to eat dead foods reliably. This is a big concern because I will be out of town for 9 days in the near future. My plan is to stock the tank with several bottles of pods prior to my departure and hope that between this and the frozen foods it will be enough. We'll see how it goes.

This is definitely a labor of love. I was talking to Cos at Calikid. I am surprised given these are all pretty much captive bred that their have not been any cool mutations developed like they have for clownfish. Maybe one day they will have an albino, longfin (err longer fin), or different color morph. Who knows. If they do that might drive up the price and make these worth breeding. My son is still getting a big kick out of these. I would love to find another adult male to try again sometime. Waiting a year for them to mature is too long.

Oh well, bummed about the loss of two, but happy about the new digs. We'll see what happens. Wish me luck!

Do you think the stress of the tank transfer likely caused the two deaths?

Yes. They were all doing fine before the move. From what I read the sudden fright syndrome may be either a nutritional issue, neuro issue, or just stress. These guys are so tiny and likely fragile that I don't really know. I could have easily injured them when trying to scoop them out since they all huddled together at the bottom corners of the tank. Live brine has unfortunately been their staple diet with occasional live pods thrown in. I wish I could figure out how to tempt them to eat other things. Oh well, this was all happenstance. Been learning a lot as I go.
 
Week 10 update:
Can't believe it has been 10 weeks already. I will admit this is getting a little old and repetitive. The good news is we only lost two fish during the transfer to the large tank. At the same time I am starting to see them eat more of the frozen foods but nowhere near reliably enough to switch from live foods.
I have been having some recent bad luck with some of the batches of brine shrimp. I suspect with the change in temperature the overall water temp for the hatcheries is too low. I don't really see a good way to warm it up that would be simple Anyone have ideas? The house is cold since we tend to have the door open for the dogs to go in and out while we are home.

There is no space for heater in the actual containers. But, I do have a small betta tank heater. I could potentially set it up like a double broiler where I place the containers in a pan with water and then place the heater in the pan. This would likely keep them warm enough. Thoughts??

With the larger size tank I have noticed the fish are more spread out now. I have also seen some more chasing/aggression which I assume are territorial disputes between neighbors. I guess they are no longer buying into the "safety in numbers" thing.

Interestingly, despite having several areas they can hide in they tend to stay out in the open water now. They have gotten use to the very large shadow that comes by several times a day for feed them. They no long dart for cover or try to hide in the corners. They are on the clock now for frozen foods. We will be away for a week later this month and the aquarium sitter is not going to be indulging their luxurious live brine shrimp meals. My plan is to stock the tank heavily with live pods prior to leaving town and hope between that and the frozen pods it will be enough. It would be a serious bummer to lose them all after all this work, but it is what it is for now.

That is it for this week. More to come next week!

I have had great luck in the past hatching brine and I’ve got the equipment still if you ever need hand with hatching food for them

You could use a heating pad under the hatchery, like is commonly used for terrariums. I think I have an extra if you want it.

I’m not personally experienced with this, but I see people freeze freshly hatched brine shrimp in small cubes, or flat in a ziplock where it’s easy to break. You could try that since it’ll be exactly the same as their normal food, just not alive.
 
Have you considered putting freshly decapsulated eggs directly in the water? Would be interesting to see if they eat the eggs, and if they didn't you could hope enough hatch that they get 100% fresh ones to eat as they grow/hatch.

You could try minimize the risk of non-eaten, non-hatching, eggs rotting in the tank by putting them in a container of some sort, or adding slowly.

Decapsulate -> rinse -> store in brine solution -> have sitter take some out and put in tank.
 
When my baby Bangaii were about the size yours are (per recent photo you posted) they would eat the little particles left from thawed Formula 1 or Formula 2 food. Maybe you’ve tried that-it would be a lot easier.
 
Week 11 update:
For now it is a lot of rinse, wash, and repeat. Have not lost any more since the transfer to the new tank. Honestly, I have been working a lot this last week which means I have not had the time to study them closely. All I can say is they are still alive. The meals remain the same, but with less live brine. Hopefully, they will figure it out because they are on the clock. In one week they are on their own or they fail. Fingers crossed at least some of them figure it out.

I have a 60 gallon cube that only has one rhomboid wrasse who finished his QT and has been under observation in this tank for a month now. I did not want him in the main display until I have time to observe closely for aggression from the other wrasses. So, for now he is the only inhabitant. I don't have enough experience with these guys, but he seems very chill. Just wondering if you think I can try putting all the babies in there with him??

That is it for now.
