It settles to the bottom, and attaches to some degree to rock or substrate, but not very firmly. It feels very soft, with thin strands, and is easy to rip apart. It grows slowly, but I don’t know if that is simply due to the low-nutrient environment.

Algae started spotting the glass in the 20 gallon. I put in about 25 shrimp from another tank. Interestingly, they have been congregating on just a few rocks, rather than roaming the tank as they do in other aquaria. I’m sure it’s temporary…just interesting to note.

Will do! I recently added a few Malaysian Trumpet Snails, thinking the others had died off, only to see a pretty large one that has to have been there for a long time. Also, I think I had underestimated the number of shrimp in there .

It can be hard to get a decent shot of a larval opae ula using just my phone, but this one isn’t too bad. This was taken just a day or two before this cohort of larvae began to molt into post-larval juveniles.

hhh they gave a feel of peace and calm, love them . Love your video

I am glad, thank you! One of the greatest things about Opae ula is how they can bring that feeling of tranquility

Loved your video..I have/had 2 berried poses and the 1st let go of her larvae..Am wondering were they went and how long before I see them..the other one will soon let go

Glad you enjoyed it!

Typically, once the larvae leave the mother, they are in the free-floating stage for about 2 weeks, more ...

The other day I was catching some Supershrimp, and removing some excess algae from the tank (not Mustafa’s macroalgae). There were quite a few floating larvae in the tank, so filmed them following the light from one side of the tank to the other.

LOTS of Opae Ula Larvae Reacting to Light!

I found a study done on coloration in long-term captive populations of Halocaridina rubra. The study indicated that while astaxanthin is the carotenoid responsible for the red color in the species, 14 days of supplementation did not appear to make a difference in the coloration. . The study ...

you have alot of tanks. Are there reason behind?

I do have a lot of tanks… I guess I have a lot of reasons, too 🤣
One is positive redundancy. If something were to happen to one of the tanks, I’d still have others.
Another is that one of the tanks is in my office at work to help me de-stress.
An ...

I kept until April before thrown out because I'm trying to observe whether there still baby inside.

About how many babies did you find in that container?

Lovely tank!
You mentioned it had been 6 years since you had cleaned up poop. How long have you had the tank?

I have been keeping Opae ula for a little over 20 years. I have a 2 gallon, a 3 gallon, 5.5 gallon, and a 10 gallon dedicated to these shrimp. I have recently set up another 2 gallon and now a 20 gallon. Here is a shot of part of the 20 gallon tank. It’s got several weeks to go before it’s ready for ...

I started keeping Opae ula back in 2004…there’s no way to distinguish the originals, as they have produced many hundreds of offspring. It’s still mind-blowing to think that some of the shrimp I have could be the originals…and that could still be true a decade from now!

I love the look of that tank! I would love to grow some Stuchenia and/or Ruppia in some of my Opae ula aquaria someday.

It is fun to see so much variety in an obviously successful, yet diminutive, setup.
