A stand and pressurized CO2 are my big two goals right now.
I am doing a driftwood and rock mix hardscape. Going for a lush look, lots of crypts, narrow leaf java fern, lots of thin leaves and grassy stuff.
I'm pulling inspiration from tanks like these
I do love the looks of Iwagumi tanks but I just feel they're not practical for fishkeeping. They are beautiful as display tanks, or tanks for shrimp, but I can't see fish being very comfortable in such open spaces. My harlequins are spazzy enough as it is without having zero cover to hide under. :P
