14 gal bio cube. The reason I asked is b'cos the cleaner shrimp has been in the tank for several months now, and I have just purchased 2 sexy shrimp yesterday. I noticed the cleaner shrimp has been chasing the sexy ones (Roll Eyes). It is b'cos of their size differents? and does the sexy shrimp serve the same purpose as the cleaner shrimp? b'cos I might want to ditch the cleaner shrimp.
