Hi. My mated pair with their pistol have been in my tank since late May but were all paired up in the LFS when I bought them. They are always out and about as a trio - the shrimp constantly burrowing for them. But the female disappeared over the past four days and I feared she died - but low and behold this morning - before the lights went on - there she was (!) peeking her head out of the tunnel. Since the lights went on, she's nowhere to be seen. I assume this is because they are breeding. I don't think she's come out to feed at all for 4 days so am a bit concerned....is this normal behavior? Anything I can do to help make them happier? Any comments you have would be appreciated as this is my first spawning event so I would like to learn anything I can. Thanks
