I have recently acquired a 10 gallon tank from a friend, was wondering what’s something different and funky I can do with it with regards to just a regular nano reef (which I already have). A species tank? Inverts? My original idea was 1 ruby red dragonet that I would try to get trained onto prepared foods. This just might not be possible but I would love a challenge! If no dragonet, then I would want to do a specific species tank. I’m just not sure what is different and could live in a 10 gallon tank. I already have a reef with your clowns and coral and cleaner shrimp, but I’m looking for something different and exciting and up for a challenge! Leave your suggestions below.
