New here and looking to get some ADF, I currently have a 75 gallon aquarium without any fish in it, would that be too large for ADF? I’m thinking of getting several (5-10). In a tank that size what would I need to be careful of? It has a heater and filter system in place as well as a lid and light. Should I get live plants? The dimensions of the aquarium are 4’ long, 1.5’ wide and 20” tall.
