Hi, what a great setup u have, so lovely. I can see a lot of larvae floating. It quite strange if u said it only breed at 72 degree. In SG here, I can only achieve 72 degree in aircon room. For my opinion water parameter is the main factor for them to breed, I did adjust my tank pH value up by adding coral chips to achieve 8.0 and bought myself a refractometer to up & maintain the salinity to 1.015. By then I realize one of my opae ula got berried. I might be wrong in this but that was what I did. But what I can see from your setup & the amount of larvae floating, your tank water parameter is very good then. Thanks for sharing the pics & info on your setup : )

Welcome to the forum!

That's great that you can get the opae to breed at 30 degrees C. For me either they would not breed at all or when a few would the babies would disappear after a day or two. All the water papameters were fine and I even separated the babies to another tank by themselves. Next day I would find them on the bottom dead. Now that the temps are down here in California 65-72 degrees I finding no issues at all.

One could very well come to conclusions like these. But on the other hand the Opaes live in so many different conditions in their habitats... it's hard for me to understand the correlations here. Since I read Hawaiian Anchialine Pools (or The Holy Book :grin3: as I call it for short) I realised that the diversity of pools is mega!

I agree with you. Hopefully yours will turn into shrimplets. For mine even it had turned into shrimplets I still not sure will there be anymore opae ula will get berried. These shrimps are very unpredictable to my opinion. Please keep us updates on your larvae progress. Thanks : )

I don't have larvae yet. I can't really say how old my oldest Opaes are. But at least 5 months or so. So they might start breeding in the near future. I guess the eggs are already sinking down :grin3: Let's lean back and see what will happen.

Good to know that those shrimps easily breed. Hopefully everything goes well for them. From there u can everyday sit in front of the tank monitoring how they progress : )

I can literally sit for hours looking at them swimming around. Let them surprise with baby shrimplets soon. :happy:

Yeah it's pretty cool how active they are. I like to watch my snails too. They can be surprisingly "fast" sometimes.

I find the speed thing funny too, you can lift the tanks lid off and if you dont watch out the snails creep out when you are not looking! :upsidedown: :upsidedown:
