i am thinking of a set up with 2 tanks and a shared sump. the tanks are going to be approx 24L x 20W x 16T. just wondering what types of horses may co exhist together and howmany horse. i was also hoping to get a few pipe fish aswell. is this tall enough for horses? the other tank is just going to be dedicated inverts and such (sexy shrimp, pompom crabs, and a couple of fish. the second tank i am debating horses and pipefish but was also pondering a mantis shrimp. the tanks are not built yet, so dimensions can easily be changed if need be, however i would like to stay close to that size. what stocking optons would be best?????????
