Pico Pest Tank

[DracoKat]

I have a standard rectangle 2.5 gal tank (I feel like it's actually smaller, I need to recheck), and I want to do a pico pest tank. Looking for some guidance since I've never done a tank this small.

A tank of just those corals and critters no one wants. GSP, Xenias, Aptasias.. rejected crabs and such. No fish. Maybe a shrimp of sorts for some activity (Donations of rejected corals welcomed!)

I can't decide if I want to go bare bottom or have sand. Trying to find the pro's and cons, so advice here would be appreciated.

I have an old HOB filter rated for 10 gals I am planning on using in leu of a powerhead- it should push enough water (of not, then I have a nano powerhead to use). I plan on putting seeded sponge from my existing sump and maybe some rubble.

I have a PAR 38 bulb for plenty of light. and a heater (may have to get a smaller one, this heater is rated for 10-20 gals)

am I missing anything? I want to keep it simple.

In a smaller tank like that you should get enough flow w/o a powerhead. Water changes are so easy! I would be careful with the gsp/xenia though, it could really take over a small tank! You could skip the sand, if water quality issues arise it could get funky. Everything sounds cool though!

I have a 2.5 gallon fluval spec 3. I use par38 abi led bulb. No softies except zoas. The rest are sps and lps. I have a 150 gallon per hr pump. Water movement is great. 10% water change every week that's it no problems here.. the last pic that has more of a blue tint is my new abi tuna 24w led. I upgraded from the 12w led. The colors are amazing with the new 24w true spectrum. Don't get the 12 w get the 24w from Abi jacobs parts company.
