Showing a dorsal filament and color in the caudal fin = male.Hi guys.
Are these male/female Mccosker/Yellow fin flashers?
Or just something else?
Thank you. Here a better picture.Showing a dorsal filament and color in the caudal fin = male.
Single dorsal filament = mckosker.
The only way one of them is not mckoskeri is that the tail of one of them appears to be developing a slight lyre shape at the top and bottom of the caudal. So it may possibly be a hybrid. However, I could just be seeing things.
With your current stock inn the dt, you should be able to add all 3 at once without the acclimation box.@evolved Hunter, thanks for your various write-ups and the "aggression" diagram! I've gotten three smaller fairy's (C. rubriventralis, C. cyanopleura & C. lubbocki) all getting along in QT together after some initial dominance displays that subsided quickly. They had been acrylic baffled off for the first three days and a week later all are starting copper after making sure they were eating well.
I do have a question for when they are introduced to the DT, should I add all three together in an acclimation box or do them one at a time? Existing stock list is two small ocellaris clowns, bi-colour blenny, cleaner wrasse, elongate dottyback and a 3" tomini tang. I'm going to get some acrylic cut and make a hang-in box, but I'm wondering just how large to make it if all three are in there. The existing fish have shown almost no aggression towards each-other, even at feeding time.
Yup, those are both sub-male mccoskeri. A 120g tank likely won't be big enough for 2 males.Thank you. Here a better picture.
If you're set on using it, I'd just put all 3 in the box together. Something along the lines of 15x8x8 would be fine for a couple days.

I also agree here - it's probably not even necessary with what you currently have.With your current stock inn the dt, you should be able to add all 3 at once without the acclimation box.

Yes, but not more than one male - independent of species.Can I put multiple leopard wrasse in a 93g cube?
Lucky you.
Just have to show off my new rhomboid wrasse. Wanted a pair for quite sum time and eventually the opportunity came up and it coincided with my birthday
In instances likes these, I like to use an acclimation box (no sand, just pvc) for 1-2 days before letting them out. This also helps them adjust to the DT photo period (if different from your QT).I have had two female m. bipartitus in QT for coming up on four weeks now. They have been through two rounds of prazi, and observation. They're both eating aggressively, and looking good. I think it is time to move them to my DT. The tank is a 220g with a mix of five resplendent anthias, two small clowns, a few small gobies, and five other wrasses (flashers and fairies). The fish all get along.
What should I expect when I move these gals to the DT? Will they go through the same couple of days hiding in the sand before they come out? Or even more hiding because they won't be alone? I've read the comments about how useful an acclimation box can be when introducing new tank mates, but the tank is pretty peaceful, so I am wondering if it would be more stressful to use a sand-free acclimation box, or just introduce the two females to the tank and let them hide until they are ready? Or put some sand in the acclimation box?
What's considered "best practice" here?
No sand in the acclimation box even for sand dwelling wrasses? Is that a special occasion with his/her situation or is that standard for shirt periods without existing Leopard wrasses? I have some fairy wrasses in the display tank, and a Leopard and melanurus in quarantine. So it would be OK to do the same?In instances likes these, I like to use an acclimation box (no sand, just pvc) for 1-2 days before letting them out.

In general, I don't like to use sand in an acclimation box - it kinda defeats the purpose if the new guy buries in the box. However, I also don't like to hold them very long in box either if they're a sand sleeper. If it's a tamarin, I'll add them in the box early in the photo period and let them out before the lights turn out - they stress too easy without sand.No sand in the acclimation box even for sand dwelling wrasses?
