Hey everyone. I have a 300L coldwater tank. I had been keeping fancy goldfish but fancied a different direction. Originally thought about tropical but heard it can be expensive to keep a big tank heated. So decided to look at smaller coldwater fish. I have had Danios and WCMM before with some Variatus platy in a smaller tank. It was a lovely mix. But now i have a much bigger tank, i am thinking of stocking ideas. I currently have just added 8 Zebra/leopard & gold zebra Danios and 6 WCMMs. I did want to put some Variatus platy in but ive been reading they actually prefer the tank abit warmer (20ish) and maybe a gentler water flow. I am undecided what i can add next. Any ideas?. Perhaps just more Danio/ WCMM combos?.
