Thanks for your tips! Finally got hold of both 白米 and 藍米 at Tung Choi Street!
白米: bought 6 (3 boys and 3 gals) of them over the weekend, but 1 of them died the next day, the rest looks healthy though
藍米: bought 6 (at least 2 boys, it seems) of them yesterday evening
Looks like I have ~20 米奇 (the rest are red) now. Thanks!
Blah blah blah>>>
Not a big fan of the yellow ones, probably because I haven't seen good ones yet! Any suggestions?
And I think my tank should be good for a while, trying not to upgrade to a bigger tank. But will probably need a separate tank for the fry when the platys start reproducing!
