Between A Rock and a Hard Place – How to Hardscape you Aquarium


If you're going to use rocks as the heart ofyour aquarium layout, then the best approach is to create at least onetall focal point where the rock formation rises at least halfway up thetank, and two-thirds of the way up. The contrast between the oppressiverockwork and the open water is very effective, and as well as lookinggood is popular with the fish, too. The classic way to do this is tosimply place three or four large, flat rocks on the bottom of the tankand then place one large slab on top of them like a table. Repeat thissort of structure across the tank to create as many caves as will berequired for the fish being kept. If you can't get rocks of theright size, terracotta pots and urns from a garden centre work just aswell, and the fish will happily use them. With a bit of algae thesepots look surprisingly good in fish tanks, and they are lightweight,relatively inexpensive, and very durable. Some aquarists like to jazzthem up a little by hiding airstones and submersible lights insidethem, creating startling visual effects.Another type of plastic decoration is the plastic plant. When choosing man made plants for you aquarium, look for a few things. First of all, look for a weighted base. The lightweight plastic aquarium plants that rely on the substrate to keep them rooted are nothing but a nuisance. Instead, buy aquarium plants that have rocks glued to the base.
