Genicanthus males - your experiences?

So, I had a female Bellus for a little over a year and was keeping my eye out for a healthy male. I finally found one and kept them for nearly 3 years with no color changes and regular spawning and spawning behavior. The male was considerably larger than the female and there was zero aggression when he was added as would be expected. He ended up becoming a bit of a bully towards my Copperband Butterfly. Sadly, I had a power outage earlier this year and lost some fish. All inhabitants were unphased except for my Bellus pair and a leopard wrasse. That leads me to believe they're a little more sensitive to either PH drops or lower oxygen levels than the average fish.

Some random notes...
The male Bellus started picking at clam mantles several months after addition. This was a very fat and healthy fish, so it wasn't because he was hungry. An unhealthy polyeasian clam seemed to start him on his addiction...


RIP



So, after a little time passed I really missed my genicanthus angels and came across a healthy little juvenille/female Watanabei



I asked the LFS to keep an eye out for a male for me... I took him home the day of arrival, managed to have the bottom of the bag blow out and have him hit the floor with a thud, put him in my frag tank in a panic with no acclimation where my purple tang proceeded to freak out on him. So, netted him out and threw caution to the wind and added him directly to my display after him being nastily tangled in the net. I fully suspected he was done for, the next tank he was a bit tattered but was eating flake food and happily swimming around the tank... Tough fish! Not even the least bit shy, he was soon gathering and nipping at my fingers when I feed like all the other little pigs.

At the same time I had picked up an achilles tang and quarantined him. A beautiful and healthy specimen, I decided to get him in the display tank after just 2 weeks. I had big fears of my sailfin tang, that I've had for nearly 10 years, ripping him to shreds. Similar fears with my longtime resident convict tang. But no, I watched in horror as the recent addition male Watanabei relentlessly pursued and ripped the achilles to shreds. So, despite their seeming delicate demeanor these can be some nasty fish. I would imagine that goes especially for a larger male since they're probably the extreme alphas of their species. Great fish, but I'll probably never add another fish to a tank that he's in that's even close to being his size.

 
How big is the risk of a male Watanabei converting to female if I don't have a female in the tank? I'm currently planning livestock and trying to decide if I need to get a pair. Do the males typically do better if a female is present?
 
I also enjoyed this thread. So if I am reading correctly just because you buy 2 or 3 females it doesn't mean they will convert to males? I have a juvenile wantanabi maybe a inch. Female for sure. I was planning on adding 2 more to create this harem. I also wanted to add 2 bellus females hoping one turned male. It almost seems and if I read correctly that if I were to do this there would only be 1 male. I can/couldn't have a bellus male and a wantanabi male in the same tank? My tank is 240 gallons
 
In most cases one will turn male eventually.Problems can occur if 2 or more fish want dominance.

If you add 2 bellus,you will still only have 1 male chances are.It could be the watanabei or the bellus.
 
So a person would probably need a very large tank if they wanted a male Wantenebei and a male bellus. Or this would never be possible?

That almost happened to me. I caught it early enough and added a female and that stopped the transition. But the male has lost the stripes.
 
I have what looks to be a mature male milanospios with very distinct vertical bars with no female. I've had him about a month now and he's doing great. Should I consider getting him a female and does it have to be a milanospios ? Sorry tried to read everything but just want to freshen up the thread.

IMO, any female Genicanthus angel would be a good addition
 
So, is it safe to say that a single male genicanthus angel will revert back to female if he doesn't have a female in the tank? What if he is in the tank with other male chaetondontoplus angel? How do you keep a male genicanthus's colors vibrant?
 
I have a Male wantanabie I bought a pair the female sadly did not make it through QT. He is 5 to 6 inches and has bin without a female for 4 weeks today.Showing no signs of reverting at this point I am looking for another female to add atm so hopefully stays Male till then.

IME, even if he did start to revert, he will go right back to male once you get the female (even a different type of Genicanthus female)

Oh kool nice to know I was told I could put another type of female. I kicked the idea around a bit I really like the Bellus but think I will keep looking for a female wantanabie .
 
I have had single fish stay males after a female jumped. These were mature males easily 4+ inches with long streamers, the fat/thick chin and were males for many years. The males that I have had change back were immature males that were smaller.

What really sucks is that females can turn male when you don't want them to... I currently have a pair of Watanabei and my female Bellus turned male (boo).

On another note, I had a single immature male Melano... turned female over a few months... added another female... the new female turned male, not the one that was kinda a male already.

These things are all Rocky Horror Picture Show with minds of their own.
 
Here is my collection.

2 species of male Genicanthus melanospilos together?

2 species of male Genicanthus melanospilos together?

Guys I searched high and low for this thread and I hope I can get some responses. I have a male lamark angel in my 150 and a female spot breast angel. I have been wanting a male spot breast angel and I wanted to know if I was to add a male SB angel to the mix, do you think both would remain male because of the female spot breast already present?
