(This is my first post on MFT so bear with me!) Hi everyone, I have recently won a goldfish at a fair and have him in a 12l tank, he is about 4cm long and I plan to upgrade to a 24l very soon. In spring next year I am going to put him in the pond with my other goldfish, (I would have done this sooner but as the weather is getting colder I didn't want the shock to kill him and also he has little fat reserves so might not survive the winter). Therefore next year I will have an empty 24l tank and I'm not sure what to put in it. I was wondering if having 4 platies would be alright, and if so, would having 2 females and 2 males be okay? I have also heard that shrimp and platies can live together so if I was to get shrimp as well, what type and how many should I get? Thanks!
