in building dividers, like mike, i've also used the plastic corner protectors to frame the divider, but i've used vinyl screening for screen doors/windows - which i guess would have the same effect as the plastic netting, although one is probably cheaper than the other (i just had some left over from a home project). i stapled the screening onto the plastic, but the staples rusted through (i thought they were aluminum... go figure). when the divider fails, i'm thinking about using fishing line (monofilament) to attach the screening to the plastic. a quick & dirty method, if you have a glass tank, is to cut the plastic a smidgen longer than the height of your tank from the bottom to the plastic lip that rims the top of the tank, so that you need only cut two lengths of plastic - staple the screening onto each side and for each of the front and back side, slide the plastic upright between the lip and the bottom glass, where it'll wedge into place. you just need to allow for excess screening on the bottom so that the fish won't dig under the screening. one thing you should watch out for is bowing. you should measure the width (from front to back) of your tank (both top and bottom) before you starting building, since i've noticed that on my tanks the width in the middle is not the same as the width on either end. i like the homemade dividers better than the kind sold in the stores (pennplax?) since the screening permits greater water flow between the divided sides and allows the fish on each side to see the fish on the other side, each side acting as dithers for the other side. however, the store-bought stuff is a lot easier to set up.... -myongsu kong. ------------------------------------------------------------------------- This is the apistogramma mailing list, apisto@majordomo.pobox.com.
