I'm now up to five after buying a tiny peacock yesterday! Thought I only had three before I got him. I'm so glad I didn't let him loose into the 30 gallon where he was going to live! I'm bending down to check if there are any snails or hermits to move out and little wennerae is watching me! So my oldest is the chiragra in a 10g, then my ciliata in a 29, said wennerae I thought had died in the 30, new peacock in the 29 biocube temporarily, and a small reddish unidentified one in my "˜tide pool' 10!
