The red algae seems to have really taken over right by the heater. I removed a lot of it and transplanted some healthy chaeto from the other side of the tank into that area.
Did not do anything regarding the gunk but I'll try to get round to it around December. From what I could make it, it is mostly pieces of dead chaeto coated with dead green hair algae and a ton of shrimp and snail poop stuck in the threads. This makes it hard to remove with tweezers, so another gravel vac is probably due at some point.
No shrimp out because I had just stuck the tweezers and scissors in plus topped up some water and they all went to hide in the back. Usually I can see about 5 or 6 at any one time.
I was also thinking of setting up my spare tank at some point, probably in the summer. It is a 10L Marina 360, so only really suitable for small shrimp. I was thinking of trying another shrimp species, maybe some purple zebras or a cherry shrimp variant. Obviously, these are a lot higher maintenance than Hawaiian red shrimp, but in a few months time I will have more time to regularly check up on and maintain a tank. After three years of opae ula, it will be good to try something new. Regardless, there is a lot of time to think about what exactly I'll go for. Might even get a third tank!

It would be interesting to try to breed an opae ula strain similar to the 'red rili shrimp'.
As far as I know they already exist! It's a sub species found in the Kalaeloa region. Not everything has to be bred! Let them be wild!
That's very interesting. Got any pictures? I looked around but couldn't find anything.
