so. Here's the whole story in shortened form. (Run-on sentence alert!! ) My friend sees my Betta, wants a Betta; friend's bday is coming soon, I had the brilliant idea of getting her a Betta and one gallon tank, did a little research on tanks and saw lots of stuff about ammonia buildup In a one-gallon, got worried for my own three Bettas who are homed in three one gallons with monthly water changes. Thats the dealio. So then I was trying to think of very basic fish that can be kept in a one gallon if a Betta cannot be safely kept (was I right on this? Or can I continue to keep Bettas in these one gallons?), and when my research turned up none, I started thinking of red cherry shrimp. Here are my questions: Can I keep red cherry shrimp in a one gallon? If yes, what do they eat, how many can I put in, and do they have any special requirements? Basically, how do u keep them? If you could point me to a website or sticky, that would be great! Thanks so so much guys! You all are awesome!
