Great option for those who don't want to use aquarium sealant... but I wouldn't like the look of those from the outside of the tank, specially because my divided tank is in the living room.
I use some acrylic molding I found at Home Depot ($2.49 for 8ft), glue it with sealant, slide in the craft mesh and cover the molding with electical tape from the outside... very clean look.
Of course, if I ever wanted to change the setup I would have to remove
EVERYTHING and scrape off the sealant... not happening!!
It would be a great option for plastic tanks!!!! Oh! My mind is rolling now with the posibilities for this... super easy way to divide tubs when you need temporary homes for fish... or to make a temporary divided tank during the colder months!! I don't use heaters when tank temp reaches 80 degrees, my tanks are all at 82 not without heaters! Gotta love South Texas weather, Ugh!
