Glass 2 and a half gallon aquarium with 20 gallon canister filter and spray bar, four pound chunk of live rock with coraline algae, glass top, coralife light. The rock itself was $40. Extra 9 watt bulbs 10000 k and true actnic blue. The tank is small but it has great equipment that can be used on larger tanks. It has also been established for a few years and has lots of small things in it such as copepods, starfish, and snails I will throw in a hermit crab.
