Bought it thinking it was a long 5 gallon. 5 betta unit tank from Aquarium Masters (ironically this tank is terribly designed for bettas). I removed the dividers and am modifying the solid glass lid for a small canister filter designed for tanks up to 10 gallons. Why call your company "Aquarium Masters" and then create a tank with no flow, no room for a heater, and no way to add filtration?! Substrate is Constrosoil over a dusting of Bacter AE. Plants will be Monte Carlo carpet, Anubias nana, Java moss or round pellia, and possibly some Crypt parva or Crypt wendtii. Hardscape is black lava rock and cholla wood. Lighting is a Finnex Stingray. I also plan to add some IALs. Right now I currently have 2 blue velvet shrimp in my old 5 gallon. It is bare bottom with mostly duckweed and pothos but I keep it grungy for the biofilm and algae (parameters are 0/0/5 so it is clean despite appearances). They are doing great. My plan is to buy at least 10 more and start a small colony in the new nano. Overall, is this a tank that will work? It's smaller than I'd like it to be but looks really nice. Dimensions are approximately 18"x6"x7"
