bluesop7- thanks, i kinda wish i still had it. my 7 gallon upgrade looks empty, but i know it will grow in just as nice. one day...
milomlo- stick with the gobies, and dartfishes, and shrimp. while tangs, angels, and mandarins that you looked at might be small, and seem like they might do well in such a small environment, they will slowly starve to death. i admit they look awesome in a small tank, but they just don't belong in there. it's best that you wait until you get that larger tank and can provide them with the right amount of food. if you want to put corals in there you will have to upgrade the lighting. i used an 18 watt coralife pc fixture right on top and it still wasn't enough light. i still use kent nano-reef for my 7 gal. and i swear by the stuff. perfect ph, kh, calcium, and trace elements too. as for the emerald crab, that's a big no in my book if you plan on having any coral in there. they will knock stuff over all the time too. fire, cleaner, sexy, and coral banded shrimp will all do well in that tiny space. you must keep calcium levels up or they will not be able to molt. pistol shrimp have a very neat symbiotic relationship with their shrimp gobies and are a blast to watch together, but the shrimp will make a mess of your substrate. i think it looks cool, the everchanging landscape. just make sure you do your research before you purchase anything, it's not as easy as you think to just pull something out later on down the road. i have five nassuras snails and five blue leg hermit crabs all the size of a dime cleaning my 14 gallon right now. a good rule of thumb is 1 crab per gallon of water. good luck!
