130 X 36 x 36 inbound...any suggestions?

There has been some talk about bloat and bacterial infections with these fish and the underlying cause.
I have only had 1 issue of bloat/constipation in one gp. This happened a few weeks ago after I fed the gp some food with purple nori. In the past I always removed the purple nori from their diet. Anyway, I fed it one time, and it led to slight buoyancy in 1 gp., that was followed by stringy poop and a couple bubbles upon release. However, others have experienced some bloat with nori free food and specific meds that were dosed during a bacterial infection outbreak.
I have not medicated the gp at all and thankfully have not experience the "upside down," "nose down," or "cave-like" swimming behavior that has been observed.
The gp do show aggression from time-to-time, I reported how I had to sequester "Killer" in an iso box for a week, this after rearranging and adding many pieces of pvc to their tank. Things were okay for a couple weeks and then "killer" went crazy again. I wasn't as harsh but there was some fin damage. I posted some pics recently. The damage, thankfully, heals quickly, and I have not felt the need to medicate.
My gp tank is cooler than many others and perhaps that is playing a factor in any bloat that has been seen.
Will keep you updated...
 
interesting ... Why do you think purple nori plays a part in buoyancy?

It's thought that there are some ingredients in the food that the fish cannot digest which then causes gas in the abdomen and the fish become slightly buoyant until they pass the gas. (It's not a swim bladder problem, but a digestive problem). One theory is that it's possible that the juvenile personatus have a difficult time digesting the purple nori because it's a temperate species and the fish are a tropical species. The adults have no problem consuming the purple nori and it may be that the juveniles just need to grow into it.

Looks like we know who your males gonna be, haha.
 
Stunning! From watching my fake Masked Angels (LOL) the male can be downright vicious with the female. He really makes sure that she's going to stay in her place, and that he'll keep his!!
I'm still so jealous!! Ugh...
Thought I'd mention, stopped in an LFS today and saw a 3 inch long TL female Crosshatch!!
If you'd like to see some pics and/or info, shoot a pm my way! I'm sure you've got your hands full but I couldn't help but think of you when I saw the little trig. Never saw one so so tiny before.
Continued good vibes to you and your fishes :-)
 
Unfortunately, the aggression you are seeing, even from small juvi Personatus, likely won't subside until they are put into your display and there is more real estate for the females to be able to flee and hide. Genicanthus males are among one of the more aggressive fish I have had experience in keeping. However, or at least in my experience, they were mostly aggressive to their female counterparts. I had a Bellus trio about 2-3 years ago and had to remove and sell the male(6.5"). The remaining females were placed in a 200 gallon tank and have suprisingly remained females. After removing the male, both females had pretty significant fin damage and had even gone on a brief hunger strike from the stress. I now have a pair of Semifasciatus, and the male has since hit the 6" mark and has started to become nasty. I am hoping the brief periods of random aggression subside in both of our cases...

lol, wish it was so easy but both male and female have black bars...I am optimistic that one will go male...if my luck is anything like the ch pair, I will end up will a trio of males and will have to swap with Drew or Todd...



Still too early but will be looking for a tail to grow streamers or some orange...

thanks for the info...
the geni hybrid trio has fortunately not shown any overt aggression over the past year and I am hoping the gp will follow the same route.

JNC,

This perspective is interesting, because it is the exact opposite experience I have had with the Bellus. I have been interested in Bellus for about the past 15 years and kept them consistently during that time. Do to a couple of crashes I have had several different males. A little over a year ago I had 2 members of a Bellus trio spawn in my tank.

Perhaps because I have a larger tank, or heavy aquascaping, or a heavy fish load. But what I love about the bellus is they have always been one of the easiest fish to keep - In terms of they don't mess with anything (fish or coral) and everybody seems to ignore them.

The last trio I had I bought the male and female as full adults. I then came across a tiny juvenile (3/4"). I am a sucker for tiny angels and took the risk. The little Bellus went into the tank, and nobody ever paid any attention to it. a year later, it was the tiny bellus that was now about 3" that I caught spawning with the male.

Interesting that we have had such different experiences with the same fish.

I think you basically proved my point :) The size of my standard 180 gallon display, and the size of Ted's QT may be what fuels some of the aggression; compared to your trio in a 400 gallon heavily aquascaped display. I think Ted will will fine once the GP's hit his display. When I had my 300 up and running, I never kept any genicanthus. I definitely believe that the more rock work and the larger the tank, will lead to less aggression amongst the genicanthus in the long term.

On a similar note, around the same time I purchased the M/F Semifasciatus pair (at about 5-6 inches each) I noticed a tiny Bellus Angel for sale (~1.25"-1.5"). I purchased the baby bellus that week and she has since been a separate tank, from the Semi's, and has doubled in size to about 3 inches TL, which is a lot of tailfin. Still looks like such a baby compared to the Semi's which are now 6" plus not counting very long streamers on the male.
I've been hoping by keeping the bellus separate and the solo Geni in its tank, it would become a male. But...
What are your thoughts on adding the small bellus to the tank with the paired Semi's? The male Semi would murder it ??

Ted- Can't wait to see those GPs in the display! I'll bet they get along famously once they have all that room !

They are in the 250...

Dave,

I'm with you, and share the same experience with the genis I have kept...

Thanks,

Hey Gris,

I am going to leave them in the 250 for quite a while.

My male Genicanthus semifasciatus is aggressive, not only towards the female, but with other tank mates as well. He certainly isn't intimidated my much...
