How often do I have to buy a new hide my pleco?

so it has had its first since about March http://www.seapets.co.uk/products/aquarium-supplies/aquarium-ornaments/decoration/natural-style-ornaments/wood-natural-decor/marina-naturals - Average daily driftwood with plants-is-what large.html that I had. so it is about 6.5 "now. every time he set his dorsal fin up to anyone touch the top of the same or gravel, depending on where he was lying. so I bought a much bigger and can stretch to the dorsal fin, without touching the top or bottom. How long will that last. http://www.seapets.co.uk/products/aquarium-supplies/aquarium-ornaments/decoration/natural-style-ornaments/rock-type-ornaments-from-resin/marina-cave-aquarium-ornament-large. html its one like this, but a little bigger, it's a Leopard Sailfin pleco. this is what http://i526.photobucket.com/albums/cc348/dragonfire_018/DSCF7028.jpg

It depends on what kind of pleco you have and how fast it grows. Believe it or not, catfish and small caches close. It makes them feel safer. If you have room in your tank for both put in and see what happens over time in. probably be the smallest one until it is too small for him to be in after the twisted around and digs out of the gravel beneath it. Another way you can get out of having to replace skin that is too often find a piece of wood that can be sustained at one end. Plecos like to scrape the wood, and he will be able to hide underneath it. While smaller, mostly sit at the bottom to the bottom which can squeeze underneath, and moves as it grows.
