Crabs in a full tank

[mellowvision]

exactly, although I first thought about it watching the end of Lost... lol..

but yeah, a ring of holes around the perimiter will create a natural waterline, with small bubbles exiting whenever the air drops below the waterline... it may not even need an airstone at the top

This bubble thing has got me thinking also...of cheese domes Do you think it would be possible to do the same thing for a turtle?

fascinating!

FFS you guys stole my idea! I wanted to do a turtle tank, but full of water and came up with the same thing.

The only real challenge to it that I can think of is balancing your pump against the airstone on top of your little cave or dome. You don't wan the water level to be too high (small airspace) but you probably don't want bubbles to escape around the side of the dome (large ugly bubbles disturbing your tank.)

I guess the way to do it is go way overkill on the airstones you want to release air from the cave, but put them at the level where you want the waer to be... so you get bubbles coming into the airspace, forcing the water level down until it gets large enough to let air out the airstones at the desired water level.

I might have to do this... just to do it.

Not to mention it would be cool to throw some red claws in my 200gal I'm building...

I was thinking...if you did this it might be a good idea to include a battery operated air pump as part of the air bubble, in case the power goes off. The one thing that has kept me from doing a river type biotope or using amphibians is that you can't fill the tank to the top. Rule number 3 says always fill the tank to the point where the water line is hidden under the trim, so if there is a scale line it is never seen. A scale line that is never seen never needs to be cleaned

Red Devil,

After rereading your original post, I was reminded of something. Red claw and fiddler crabs don't get along with each other as well as they do with their own species. In particular, they really go after the other when one molts.

I don't think a battery back-up would be required as the crabs do not need constant access to the air. Even if you lost power for 2-3 days the crabs should still be ok until power was restored. Thoughts?

you're right JH, they would be fine if the bubble filled up with water.... but the design I am working on wouldn't fill up if the pump failed... the air might get stale but would remain.

Well, from what i've read...

They either do need air.

Or they actually don't.

Honestly, i've read, on multiple occasions, both. I've actually got a crab in a full water tank right now, i had only read the 'don't need' articles. He's got a Rainbow shark, some angels, and quite a few others for company. been a week, and she comes out at night and in the early morning.
