What Fish To Add To My Tank?

[elliott1]

Hello,
I Have a 20 litre tropical fish tank with a heater,filter and light. I currently have a male betta and 5 black neon tetras.
What other additions could I add to my tank without it becoming overcrowded

Boy you are pretty much stocked. Snails. You might be able to do some cherry shrimp. That is a tiny tank. I would work on getting yourself a 10 gallon for those fish and ditch the 5 gallon.

Is that right; 20 litres? If so, I'd say you were overstocked already in all honesty...

if I keep the tank as populated as it is. Will it be okay. They seem to be staying away from each other at the moment
thanks,
Elliott
