Rummy nose tetra in 20 gallon long
Can rummy nose tetras be kept in a 20 gallon long? And if so, how many? Thanks.
They're pretty sensitive to water parameter fluctuations so... keeping them in a smaller tank is always a risk. I never had much luck when I had them in my old 20gal, but then, I wasn't a very experienced aquarium-keeper at the time. They should be fine as long as your water is stable.
