I've just got a new 3ft tank (thanks Mystic! ) and would like to use it as a breeding tank. I would like to be able to divide it up 4 sections longways, and also each section in half again.
I want each divider to be completely removable, and to leave no residue. I also would like only one filter and heater, so water needs to be able to flow through the whole tank.
I was thinking of putting in acrylic dividers that are slightly smaller than the internal measurement of the tank. I would use airline split lengthwise to get the acrylic divider in and out, and to create a seal.
I am planning on leaving about 3cm below the divider, and putting a sponge underneath (then I wont have the issue of needing a perfect fit at the bottom) so fry can't get through, and to allow water flow and bacteria to grow. The tanks will be barebottomed, so area for bacteria growth should be good.
I don't think there will be enough water flow under the dividers, so I need to have some sort of holes in the dividers for water. I could either drill/laser cut small holes in the acrylic dividers, or cut a big hole out, and stick some flyscreen over the hole. That would allow better water flow, and wouldn't get clogged so easily.
Is this a good idea? How much smaller that the tank should the dividers be to create a tight (but not too tight) fit with the airline hose?
Am I going to potentially be able to have small dividers dividing divided sections in half? (wow that's a hard sentence! - see pic below)
Feedback would be awesome, thanks!
