Ok so i will be moving december 1st and probably selling out of almost everything i have besides maybe a few select pieces of equipment. I will for right now be keeping the frag tank (24x12x7) its about 7.5 gallons so it is shallow and it has a 18 LED fixture over it (12 blue, 6 white, white driven harder) It is on a small 2 drawer end table right now and it is viewed from top down.

I am wondering if i sell out of all my frags and stuff what are some ideas of what i could put in that tank? it will just have a small hang on filter and right now i have a K2 in there but might downgrade to possibly 2 koralia nanos.

I am thinking sandy bottom with little liverock boulders throughout the bottom and maybe just doing an invert type of reef flat with some brittle stars and shrimp and crabs.

another idea was get a n. wennerae mantis shrimp like i have had before and put him in there.

i think the height is too small for most seahorses, i cant really think of any other ideas. i am going to keep with the LEDS for now because i can always add some small frags of things at any time or some cool reef plants to it.

Also, if i did do just inverts and easier coral what would your opinion be on the use of RO/DI? i would only do a gallon or two water change weekly/biweekly but is it really necessary to use RO/DI, i would have to check the tap TDS on the new place first i would assume. i can always feed it with microbacter i just dont want to have to hook up a RO/DI just for a 7 gallon tank. i could always get some off my buddy or go to fish docs and pick some up if its needed.

Give me your thoughts on what you would do with this tank instead of having it as a frag tank! i want to stay somewhat in the hobby for now but until i get it all figured out i figured this small tank should pass the time pretty good.
