I haven't thought of invertebrates but I'm glad you mentioned them! It sounds a lot easier since these animals can actually be kept with ACFs afterwards. I've always wanted shrimp, but I'm afraid their population may get out of control? I heard they breed really fast.

Also I wanted to ask, how do you change your water in your huge tank? You prepare 5 buckets of water a day before changing it? Or do you have a larger container for it? And when/if you go on holiday, do you just ask a friend to come in and do it?
