Well it did come with 2 75gals. I'm hoping a 75 with an FX6 will be fine until I get my 1,200 gal built. Little Mbu is only 4-5" right now. The LFS "1 gal per dollar spent on fish" was too much to resist. I now have a solution to my snail problem. Can I just move to feeding it Costco green mussels/shrimp by the bag once it is bigger? I'm guessing local caught (nerfed.. clip clip) crayfish may also be good. Should I name it "Nibbles"? 1 of the 75s will become a sump once I build the 1200.
