I think it looks fantastic! The dwarf hair grass has a really awesome green, especially in contrast to the dark substrate. How is the flow with 2 power heads and the canister? Also, I think you should add a school of corys for the bottom. I think they are great fish and some sterbai or julii corys would look great with the dark substrate.
Thank you!! The flow is alright. I think some of my fish like playing in the current the powerheads create. I would add some corys but I don't think they would have any room to swim. Maybe I should have gotten Eleocharis Belem which grows shorter than the dhg I have now. I'll definitely look into though.
