Just an update as it has been a pretty long time. My opae ula are breeding each summer like crazy, I went from 8 oape ula (after the second start) to around 200 right now :-)
The aquarium looks pretty nice with all my friends swimming around!:-)
Last two years I only have one snail and he seems to be doing pretty well. As my group of opae ula expanded this much I will try to see how the aquarium evolves without the snail (whenever he decides to die)
