75 Gallon Tank Fry tank divider, what materials, & do they need holes?

I recently posted about a DIY tank divider I made. Although it works well, I realize I need a more permanent solution since it does have a lot of small holes the fry can escape through. I went to my local fish store and they didn’t have a tank divider for my sized aquarium(75-gallon). Ordering from Amazon would take too long. I found this material that is at my local Walmart and looks like a net (I went to buy some soft small net material but couldn't find any anywhere). Would this "Aida cloth" be fish-safe? I've never worked with it before so any pointers would help. If there is a better net-like material please tell me! I just have to make sure it's really fine so that my angelfish fry can't swim through it.

 

Can you make a wire frame and have it wear pant hose as a quick fix?

 

Have you looked at craft mesh? it’s a bit firmer than net & I found it worked quite well when I had to temporarily divide a tank.

what do you mean by pant hose?

How big were the holes? My only concern with it is that the holes might be too big and that my fry will escape to the other side.

with the one I used cory fry didn’t get through & I don’t think angel fry would either. I think you can get different sizes in it, have a look on Amazon or similar & see what you think

 

what do you mean by pant hose?

I mean women's stalkings. You may not have to cut it to put around a frame, that's why I said "wear", like put the frame in it and maybe stitch the edges.

 

DIY Dividers

 

I went to micheals and found this plastic material that would work great! Thank you for the help though

My DIY tank divider is just a plastic sheet (shaped like cardboard) in my tank. I don’t want to put wholes that are too big since I have angelfish fry in that tank. The divider is positioned so that the intake part of my filter is on one side and the output part is on the other side. Since I have it set up like this, do I still need to put holes in it?

I would say yes otherwise I don’t see how there would be much/any circulation between the two sides. From the pictures it looked like you’ve ultimately created two separate tanks.

 

I would agree with Demeter. Maybe you can poke holes too small for the fry to get through.

I agree and the side with the output won’t get any filtration

 

Just leave it like that and get a dual output airpump and get 2 small sponge filters , otherwise i would also add some holes. But then again more tanks are always an option as well.

 

It's not obvious from the picture - how is the water currently flowing? Up and over the top of the divider?

Obviously, if the filter is on and pumping the same amount of water as normal and one side isn't overflowing, then there is still water flowing from the left side to the right in some way. Although not ideal because the water isn't circulating as it normally would, both sides are still getting some water input and output.

 

Maybe you could cut slits in the divider so that water can flow, but fish can't get through

 

Yeah I figured as much. I’ll drill small holes towards the top of the divider just to create some extra water flow. Both sides are level so I’m assuming there is some way the water is flowing.

Good point I didn’t think about the water level

 

There’s an issue with water changes you will find out about soon enough when you siphon water out from one side. Even with these ready made clips the divider will move as the water pressure pushes on the high side. I would definitely suggest you have a cycled filter or two on each side of the divider.

As it currently is set up the one side will not get satisfactory filtration.

No need for holes . But you need more filters.

Maybe not two box filters and two stacked sponge filters with a ziss filter as is in this 40 gallon with just a handful of fish?
