I recently set up my old 5 gallon standard to try my hand at high tech. I scored a bunch of scratch and dent plants at Petco that were half off. Well, after about a week it decides to spring a leak. Just one day after we spent two hours separating and planting hairgrass! So, I just rescaped our 5 gallon koi betta and 6.8 gallon delta tail betta tanks. The 6.8 looks a bit rough at the moment until the DHG and Ludwigia fills in. Anything I can do to improve these tanks, please let me know.
