Tips for DIY "Built in fish tanks".

Wall aquarium fish.


The general rule for fish in a thinner tank is to make sure the fish will not grow too long.  Your fish should have at least a 1” space between them and the walls however 2 ½”+ is recommended.  That means that if your tank is 6” deep you should have fish 3 ½” or smaller or if your tank is 8” deep your fish should be around 5 ½”.  The good news is that most aquarium fish fall under this category.  You can refer to these charts to help you choose.
