Oooops. Lol. Be careful what you wish for.
This thing is tiny. The 1 3/8" she was listed at was generous and included the tail. I guess I just didn't realize how small this fish would be.
My plan was to section off a corner of the tank using egg crate for her to live in while the other lemonpeel got used to her being there. I've abandoned that idea for now because it may be possible for her to just fit through the egg crate if she went diagonally. Not sure but it looks close. Instead I've outfitted an overflow box with some pvc fittings and a couple little pcs of rock for shelter and hung it on the side and that's where she currently is. The other lemonpeel looks enormous compared with her, as do the other fish. It has definitely noticed the new one but only looks in from a distance of about 6" away from the box and for only a brief period before swimming away with no obvious thoughts on the matter. She still has obviously traces of her eye spot so I'm not sure how that plays into the decision to kill her, mate with her, or ignore her.
The fish is perfect, of course, coming from DD. Just beautiful.
So what to do? I could test the egg crate in her current overflow box pen to see if she can get through it. If not I could go back to that idea. That could work for a significant amount of time. I suppose it's possible that even if she can get through it then she could use that corner as a refuge, but that may be asking a lot of her intelligence, and luck. Beyond the intraspecies aggression possibility I'm afraid that the 4" niger trigger may decide she is planktonic food and try to sample her. I have no way to know what he would do, and he is fast and crafty and always hungry.
Another tempting option sitting here is a 16 gallon nano tank that was set up about 2 weeks ago and is currently empty of fish. She would be perfect in it until she got a little bigger. Unfortunately as I mentioned it was set up only 2 wks ago with dead base rock and filled with water from the main tank. It may have cycled some but is not "established". I suppose it is no worse than a typical quarantine tank. I have put some small pcs of nicely crusted live rock in there from the main tank now. This could be a good place for her to grow out, but I'm a little concerned about the stability of the small tank. And it wouldn't get me my pair. And I suppose there is the possibility that leaving her alone for too long could prompt her to convert to a male, based on what I've read, but I have no idea how long that might take especially as young as she is.
Or maybe I'm being overly cautious and she would be fine in the main tank.
Well, I'm thinking as I write this so it is not very succint and I apologize. I would welcome your thoughts!!
