Well in my 2.75g 2 - 20w 50/50 coralife screw ins, aquatech 10/15 hob (no media) also running a 56gph powerhead now (the far side from the hob was starting to have cyano issues) I keep:
Animals:
1 Redheaded goby
1 nassarius snail
1 scarlet hermit
Corals:
Brown clove polyps
Green star Polyps
White star Polyps
Brown, Green and Orange Montipora digitata
4 zoo frags (Green with orange centers, Brown with green centers, brown with green/orange centers, and red with a purple mouth)
Branching Hammer
Ricordea (multicolored - green, yellow, purple, some red - yellow mouth)
a striped shroom that has recently dissapeared (guess I should have glued it down)
Candy Cane
My 20g Pred tank, 10g sump (Planning an upgrade - 20g sump, with properly done DSB, and chaeto, plus an in sump skimmer), room lighting - soon to be some NO flourescent 03s (lion doesn't come out much when it's lit up); coralife super skimmer. Water movement's handled by an overflow & quietone 1200 pump (another upgrade in the works - going to switch to a mag 5 and add a seio 620)
Residents:
Dwarf fuzzy lion
Juvenile Green Dragon wrasse (he's just over 2" - he'll be moved to a friends pred tank when he's big enough not to get eaten by that tanks current residents)
No corals, cleanup crew is on the decline (wrasse loves them snails/hermits). Pondering trying some of the predatory corals once settled from the upcoming upgrades.
