I have an established 55 reef tank so not a newbie but I have just picked up a 29 gallon bio with the purpose of a very tranquil tank. I would like to set it up and get it well established before adding livestock. I want to have some dwarf horses and maybe a couple of mandarins. Obviously will need cleanup crew etc but want it to be about the horses. I am very patient and want to get it set up correctly. The 29 was my parents tank that they decided to get rid of once they upgraded so tank is not new out of package. I want to add some rock but not overdo it and will need some grass etc for horses. However my question is should I add pods, brine shrimp, HI red shrimp or anything else to get a good food source established? Has anyone done this before? Please help direct me if you have any advice.
