They will ask about your tank when you buy them and they don't seem to understand these are actually brackish snails so if they do ask you about anything you need to say you have a fresh water tank that does have filtration or they wont sell them too you. :angry: :what: :sad:

Just wanted to say because if you say they are going in a brackish tank with no filter/heater/pump etc they will say no to the sale lol.

I raised the temperature on the heater slightly a few days ago and since then new brown algae has stopped growing on the sides and top of the tank, although what was there before is still there. Some green algae has now started growing between the rocks.

That's interesting, what temperature do you have in the water now?

It was at about 24 degrees C (75 F). I raised it to 26 degrees C (79 F) because Hawaii sea temperatures tend to be around that.

Also, I think I will purchase some more opae ula further down the line. Whenever I look at my tank these days, it seems there are only 2-3 around. I am sure there are many hiding, but even then I do not think there are more than 12 left. I added 22 in total. You can see in my older photos there used to be large groups gathering together. I think a lot more died off when I had the nutrient spike than I had initially counted as dead, so it would be good to repopulate.

The green algae between the rocks at the left side of the tank has grown very fast, expanded substantially since I last saw it 6 days ago. It resembles the 'angel hair moss' from this person's video:

I will take a photo later on.

That's good news, id expect some green algae and things growing after this amount of time. Keep us updated on how it progresses over the next few weeks.
