I am going to get a bigger tank for my Betta and the current one 5g (20 litres) I would like to use as a shrimp tank. So I have few questions - can I keep cherry and red nose shrimps together? How many of them would be okay for 5g tank? I will also get some new plants for both tanks - so any suggestions which ones are the best for shrimp? Anything else I need to know? And will I be able to introduce female Betta in to this shrimp tank later on? Many thanks in advance for your advice and help!
