Red hooks

[steve_b]

Just grabbed a few snaps of my red hooks to share while doing a water change. They don't usually get much attention as its mostly about the rays, but they are a great fish.

Currently I only have 4 with the biggest being about 7" but Im looking to add 2 or 3 more to the group.

Curious...How are you determining sex on them? I see spotting on at least 3. Are you using the thickness or color of the fins? Redness around gills and mouth? It's my understanding that they are not sexually dimorphic. I'd like to know if there is a reliable way to sex them... I have 2 shoals and the only sure difference I see is the sparring between males for dominance after water changes or feeding time.

I was told females have a real prominate hook shape and males hook shape is straighter less hooky

Males have a bi-lobed anal fin. Females have a straight anal fin.

If you look at the ones in the first 4 pics with a long single red/black hook anal fin, those are females. Now the one in the back in pic 5 with a bi-lobed anal fin almost like its developing a second hook is a male.
This is a typical way to ID Silver Dollars.

Yeah they are skittish. A couple of days after posting this I walked past the tank and the only male spooked and hit the side of the tank so hard it turned upside down and died a couple of hours later.
