Pokeshrimp Posted March 20, 2016 Report Share Posted March 20, 2016 http://www.crabhomes.com/product/1/4/Underwater_Island.html has anyone tried using this before? I'm working on turning my 40b tank into invertopia and some crabs would be pretty rad. Quote Link to comment Share on other sites More sharing options...

Pokeshrimp Posted March 20, 2016 Author Report Share Posted March 20, 2016 how do they get air? I've seen one made out of a jar and they used an airline to get air to it. Quote Link to comment Share on other sites More sharing options...

sarah Posted March 21, 2016 Report Share Posted March 21, 2016 I'm sure everyone here knows this already, but just in case someone new is reading this thread - it's important to know that fiddler crabs must be kept in brackish water. No matter how they sell them at the store, these crabs will not survive in freshwater for long. Also important to not overstock (most places recommended a 1:3 male to female ratio, but I had one male that eventually killed all but his one chosen female). They need space to create and defend their territories. ShrimpP and Soothing Shrimp 2 Quote Link to comment Share on other sites More sharing options...
oem Posted March 24, 2016 Report Share Posted March 24, 2016 My sister did something similar with her outdoor Koi pond but reversed. She stationed a 2.5 Betta sphere upside down on bricks. Now the fish can swim up to see the rest of the world. Quote Link to comment Share on other sites More sharing options...
