Thank you! I've come across that as well during my research. Never really had an issue with my old tank and my current tank only has a single acro in it. Hoping that the it won't be an issue if I keep them well fed - albeit I've been away from my tank due to travel quite a bit the last 2 weeks.Cool tank, very similar to mine. I have heard that sexy shrimp like to much on corals, have you seen that?
