I've just popped 3 into my tank and are approx 2" in size, so they aren't going to grow anymore. I may introduce my LR with Aips on in the next day or so and see how they get on. Just found out that they only live around 2 years and cark it :huh:
I also came across this videos and on one hand it seems a good idea but time consuming.
I'm also thinking of getting another 3 and teaching them synchronised swimming :smiley:
