Just set up my first tank in 40 years, 650 Ltrs (170 g) with Sump filtration. Planted with CO2 injection and inline UV. Freshwater tropical community is the goal. I know I’ve gone big for a first tank but was told bigger is better (behave!) and hence I went all in with my set up. Now wondering what to put in it lol. We’ve started it off with 20 Rummynose Tetra’s and 17 Cardinal Tetra’s, but not sure what direction to go in next lol. Helppppppppppp
