Sometimes selecting the right fish that can live happily together can be quite a challenge. It requires some knowledge about each species brought aboard, and their sometimes unique needs. In addition it is important to understand their numbers, in other words, how many members of each species can be introduced safely based on your tank size. This section was created to help new comers by providing real samples of freshwater communities. We will continue to expand it, as we get more feedback from our website users. Please bear in mind that if your aquarium is new, you cannot add all the fish at once. Depending on each species’ ability to withstand the hard conditions present at the beginning of the cycling, we will give some advice on which fish introduce first. Be patience, it takes 4-6 weeks to cycle a brand new aquarium. In the mean time it is important to test the water for nitrite and ammonia on a weekly base while this process last.
