Soo what your really saying that the profile and bryon are wrong, which is highly unlikely. What we said is based on proven fact. There is a 50/50 chance that you'll end up with a breeding pair, to to the fact that angels are only sexable during spawning. And yes, they do school and the wild and to make them as comfortable as possible, we try to recreate this. This also helps with aggression.
Why yes I am. Call me bold but I have some evidence. These are post from VERY experienced breeders and angelfish keepers.
Here's a few of my reasons:
I agree, I'd go even further and say that 2 spawning pairs in a 90 is pushing it.
People usually get these fish when they are small, they see them schooling around in the pet store tank and think that they behave this way normally. Unfortunately as they grow up they (like most other fish) lose their schooling behavior and can become aggressive, especially the males when they pair up.
Yeah, they are not really true schoolers like most tetras are. They are territorial fish. Not to mention I would not put 6 angels in a 55g for the long haul. But, fishkeeping yields multiple results and differing opinions. I think you were quite right in suggest an angel or 2 for that tank. JMO.
They do school together, but they are not true schoolers. Since they break up and defend their own territories as part of breeding, thats what makes them not "true schoolers." But yes, they do indeed school together. Good point.
Sorry if I'm partially stepping out of line with this, but I have experience on my side with this.
