Still dreaming

[ejaustin]

I'm thinking about my next tank, as I often do. I'm thinking it would be cool to have a sort of in-tank refugium for pods. Like put a little cave of live rock near the bottom of the pile with openings too small for fish to get in there to eat too many of the little guys.

1. Is there a good reason not to do this?

2. If I do this, do I need to come up with a way for them to have some light, or are they okay in darkness?

3. If I do this, is it more important for them to have sand area or water volume?

People often do this in nanos (where fuges are often not applicable) by simply having a pile of small rocks or shells. Sometimes they even put a sponge in there, but be carefull as that can become a souce of excess nitrates.

I think it'd be an ok idea. The only drawback is its a good place for detrius to collect. I don't think lighting would be an issue since some light would still reach them.

Agree with John on this one, great place for detritus to accumulate. An easier option would be to establish a refugium above tank so that the pods harmlessly gravity drain back down into the tank.
