于 2003-03-01 12:00 I’ve set-up a new 40X24X24 tank last week and put 3 魔 in my tank for the nitrogen-cycle to prevent the”new tank sydrome”. However when I visited the same shop yesterday the keeper persuade me to get few more fishes(魔) for my 40” tank. He said merely 3 fishes won’t be able to provide enough food (屎) for the healty-bacteria to set-up the efficiency cycling……….Does what ‘d he say is true? Should I get few more fishes? 3 fishes not enough?
