Since I've been advised that my 54 liter aquarium is too small for Trichogaster Lalius, I'm wondering if it is a suitable size for Dario Dario. The tank measurements are 42 x 40 x 44,5 cm (length x width x height). If it is a good size, how many can I keep in it (male and female) and could there be any tank mates?
Cheers,
Jonette
