In the biube tank instructions it says that you can only add 1 small fish every 28 days. However, I have heard that this is not as true as it seems. It says in the frequency chart that you can have 3 small fish every month and I wondered that guppies would be small tropical. Any advice would be much appreciated as I only have 1 solitary male guppy and would like to stock the tank sooner rather then later. If I waited the recommended number of days I would be looking at stocking this time next year. Thank you.
