Do you think i can keep emperor tetras with my angelfish I have just bought 2 gold glitter angels (2" tall) for my 20" cube tank and want to add 6 emperor tetras. Will they get along or will they end up as food??
125 litres is 33 gallons - more than fine for a pair of angels and some dithers. They're often bred in 20 highs, and a 29 gallon tank is more than adequate for a pair.
