應該點樣照顧紅劍嘅bb

最好是分缸，如無地方的話，買個ＢＢ缸放在原缸內，將的ＢＢ放在ＢＢ缸內養會好些，可以將些紅蟲「啄」爛再餵給牠們。

Hi, I am Derek Tong, I suggest that you should 分開 the big fish and small fish. Buy a 17cm X16 cm 缸 ($7X) will be suitable, then you don't need to add a filter, because it likely put the babies inside it. Add a 'bum' ( $30 )for the babies to provide oxygen for them, you also need some seaweeds( $15-25 ) for them, babies can recieve some neutions from the seaweeds. It's November now, the weather will be cold, add a warmer ( $80-$120) to control the temperature between 23-27oC, so that you also need a therometer ( $10 )to observe the temperature of the water. A light (Over $100 ) is also important, the fish can grow up healthily under the lights.
You may buy the fish food from M.K, there are some tiny fish food for babies.

Don't change the water too much, it's not good for the fish, before you change the water, put in somewhere to make sure that the 'Green Gas' has gone.

Hop that my opinion can help you!
