Stocking ideas for 50 to 65 gallons Fishtank

Aquarium stocking ideas: the 50 to 65 gallons fishtank

You have decided on a aquarium and already set up your fishtank? If you have chosen a tank that can hold between 48 and 60 gallons, you have chosen a good starting size. Not only is the selection of the fish with a tank-length of 38-48 inches as limited as an aquarium that only holds 20 gallons (24 inches long), it is also substantially easier to maintain such a fishtank and one has a larger area for decoration and plants. Larger fishtanks  forgive various beginners mistakes much better than their smaller counterparts, which, for example, are quickly caused by too much fertilizer or pollutants in the water. And even if the weekly partial water change should fail once, such a fishtank does not threaten to "tip over".

For all those who have decided for tanks between 50 and 65 gallons, we have provided beautiful and harmonious stocking ideas in the following article, which should not only support you in the selection of the fish, but also avoid the typical beginners mistakes in the selection of the setting.
