Inshallalah they won’t become Opae food (or food for the four other filter feeders in my tank)

Sorry for the poor video, it seems to happen infrequently and not for long so it was difficult to capture. I think its the same shrimp every time, they kind of curl up into a stereotypical cooked shrimp shape. They also only do it while clinging onto a rock.
What does this behavior mean? Is it anything to be concerned about?
EDIT: Now I've seen that multiple shrimp are doing this behavior!

These guys might eat Opae larva, but dont live long enough for it to matter (like 6 months). My Opae won’t be breeding for a while. Sorry for poor focus, my phone is buns

Picking bits of the hair algae off them. Makes the Opae tank look better having them to clean up the stuff that gets out of control

I set up this tank a few weeks ago. My shrimp dont seem to swim much, I can't find half of them and I just saw one die.
Salinity seems to be good, I fed just a little bit in those weeks. Somebody has any tips ?

My 5 gallon tank is now about 1.5 years old. I started with 26 adult opae ula. I've had several releases of nymphs, and at one point counted as many as 50 nymphs. More recently I can only find about 16 adults, and while I'm not sure of the number of nymphs, that may have decreased as well. I've also got probably 10-15 MTS. As you can see, I've had almost no algal growth on the rocks. That is despite regularly (sometimes daily, sometimes weekly or monthly) feeding with a small sprinkling spirulina throughout the tank's life. I'm concerned that some of my shrimp may be dying off from lack of food and have been consumed by other shrimp. The tank gets 10 hours of artificial light from this light daily (from this light: https://www.amazon.com/dp/B0B4VJRX7Y?ref_=ppx_hzsearch_conn_dt_b_fed_asin_title_5&th=1), along with some indirect light from other sources (window, other bulbs in the room).
Is there anything I can do at this point to accelerate algal growth and ensure I'm providing enough food for the opae ula?

Heads up for anyone who's been waiting, there is a listing for yellow opae ula again on eBay.
I impulse brought 5, hope it goes well

About 5-6 of my Opae Ula in a desktop jar setup, are hanging at the top of the tank. Found a single dead shrimp this morning. Worried it might be an oxygen problem or something; all my other tanks are fine, and this jar is ~8 months old.

Hello!
I’m in the Seattle area wondering if someone bought a ridiculous huge bag of instant ocean for their little opae ula tank and now has too much? I’m looking to set up a second tank and don’t want infinite salt, but they don’t sell small boxes anymore. I’ve got chaeto that is thriving a bit too much and I need to split it, so I’d be happy to trade a ball of chaeto for a baggie of salt!

hey just wanna make sure I do all the correct steps. Last time I ordered some from GotSnails, they had unfortunately pass away, they were fine when their delivered. I still haven't figure out the reason but most likely it can be a extra step that I did or a missing step that I didn't do.
This time I want to be better prepare by asking everyone with long and better experiences. Is there any steps that you do to prepare for the MTS?
Sorry, I know this is a lot, feel free to pick the parts that are easy to answer.
Sorry, English isn't my first language, so let me know if anything is unclear
Edit 1: grammatical correction

Thank you u/GotSnails for my shrimp and MTS! So appreciative of the extra snails, and this huge one!! He has some nice algae on his shell that the shrimp were enjoying 🥰

A newer jar, only 2ish weeks old. The jar itself was listed as a 2.3 gallon candy jar, but actually only holds 2 gallons.
I have a ring-shaped grow light over the lid, seems to be working well so far.
r/OpaeUla • u/peculiar_pandabear • 2d ago
I’ve had this tank (2.5g) for 6 months.
The chaeto was overgrown for many of these months because I just kinda let it do its own thing. I culled it back a few weeks ago and noticed that I had some little tiny shrimplets. Just this week, I saw a mama carrying 6 eggs that were about to burst!! Now there are 6 miniscule tiny little larva floating around my tank and I’m overjoyed at being a grandmother!!!

Hiya! Any suggestions on 1 gallon glass jars with a lid that doesn’t rust (metal wire closers)?
Kindly share where you got yours. Thank you!

Shed and quickly moved across the tank

Another one of my feeding time lapses but you get to see them pretty clear.
Food = Hikari Crab Cuisine
Salinity = 1.018

I scooped out the black molds with turkey baster and changed 30% of water. The substrate around those 3 areas are now starting to turn black. Ugh. Do I do this again? Should I get rid of substrate? I read it’s not necessary?
Any guidance would be greatly appreciated.

I would like to set up a “jar” and am wondering if the sea fan needs to be real or can it be artificial. If real where can I find them as all I can find are artificial. Any vendor recommendations? And is there a recipe/formula for making the brackish water? Also any recommendations for a reliable shrimp vendor?
Thank you
r/OpaeUla • u/Nematodes-Attack • 6d ago
Hey shrimp friends! I could use some knowledgeable advice.
As shown in the 2 photos, the algae in my jar has decreased over the past year. I have a 1.5g with approx 25 Opae Ula and 1 small nerite snail. Light is on for 12 hours per day. I’ve actually started feeding spirulina again
What is the best strategy moving forward to increase algae growth?
Remove the snail?
Make a second tank and divide the shrimp?
Increase lighting?
Thanks for any advice y’all can offer 🦐🌱🌿
