Assessor randalli

A couple of weeks ago I made a rare find: a single Assessor randalli.

Here a video of it in one of my QTs:



Now I just need to find him a partner...

That's kind of my plan with him - he goes into the tank with my yellow Assessor pair.

Well, the little guy didn't even make it through the night... ;(
So I guess I need to continue searching.

Very cool fish. Sorry that the little one didn't make it. The one in the vid is still alive, right?

I haven't seen him for a while, but that's nothing unusual with these guys, especially not in a tank that has more cave than open space.
I also suspect that he and the yellow ORA captive bred one have paired up and are spawning. At least, the yellow one always looks gravid when it comes out for food. With my wild Yellow Assessors the male is not to be seen for periods of time. This would mirror the breeding behavior of Marine Bettas.

Get a second one and you will see them all the time. My Marine Bettas are out frequently, especially during feedings.

Got 2 more on Saturday. These last 2 are bigger than my first and I might keep them on their own as I've never managed to keep trios to get along. One always got killed of by the other two once they paired up and started spawning.

It depends on the one you already have.
If it is a small one I would add a bigger one.
If it's a large one it gets a bit trickier because then it's best to get the matching partner.

when you say matching partner, you mean size wise? My current is about 5 inches head to tail. good weight. So I should try one as similar in size to that? thanks for your time.

No, male or female. At 5 inches it should still be female.
How large is your tank?

180 is more than enough for a pair.
You can sex them best by their genital papilla. The ones of females are rounded like a well-worn pencil tip while the ones of males are more pointy like a newly sharpened pencil tip.

This is how the genital papilla of a female looks:


Males also have somewhat longer ventral fins.

Male:

Do you have your assessors in the same tank as your marine beta? I suspect mine has eaten mine, some neon gobies and possibly a fire fish or two. My beta is very good at hiding for such a large fish. Does your pair spawn?

I never had Marine Bettas eat fish or even show interest in eating fish. In my experience all they eat are pods and shrimp (and all kinds of dry food).
My Marine Bettas usually don't hide at all. My Assessors on the other hand are the Masters of hiding and I hardly ever see them in tanks with larger or more aggressive fish they feel threatened by. So maybe your Assessors are just hiding. What other fish do you have with them?
All 4 Marine Bettas I have are still females or juveniles, so no spawning yet.
