Think this will prevent jumpers vs full lid?

Saw this 3D print project while looking at options for my rimless tank. Think something around the the edge the hands over the inside of the tank by a few inches is enough to catch any jumpers?

I think it would protect the edges for sure, and help prevent jumpers. But there's no stopping them from getting a running start and coming from the center :grinning-face-with-sweat:

A fish could jump through any open spot.
Many have had them jump through the tiniest of openings.

Only a full coverage lid, mesh or other gives you complete coverage.

I'm going to assume no. A lot of us (myself included) use egg crate with half inch square holes. I personally have lost a Halichoeres garnoti, a Diamond Goby, and almost a Macropharyngodon meleagris through those.

Unfortunately some fish are going to jump if they see a spot big enough to jump.

In my experience, *most* fish do squeeze out at the edges of the tank/lid. I believe many get spooked, then shoot across the tank where they hit the glass, and then shoot straight up and out of even the tiniest gap between the tank and the lid. So I do like they way this design addresses that, and I think it may work well for freshwater fish.

But, there are PLENTY of marine fish that will just take a flying leap out of the open center part. Then, you have a $100 carpet-dried cat snack :-(

There's plenty of options for DIY screens and inexpensive tops, including egg crate, which you can line with some screen or netting to keep fish contained. And of course, there are custom lids available from places like Kraken Reef you could explore too. But I would encourage you to cover the whole top in some way to keep your fish safe.

I REALLY lucked out with my last tank. No cover and not one jumped out over 5 years. That being said, I ain't gonna tempt fate again with my next iteration.

In a word, no.

Wasn’t sure if they would free Willy it like that from the Center or if they’d just try jump over the edge/lip of the tank hahaha

Yeah I planned on getting the Red Sea DIY kit just waiting for a restock from my fav site to order from but saw this idea and thought it looked nicer. DIY net top it is. Haha

Any guarding is more than no guarding, but no it will not go very far to prevent jumpers in that configuration. Looks more like a waste of plastic to block some light to me.

Agreed. And eggcrate is not small enough. I had a blue dot jawfish jump out of a tank covered by eggcrate. he was big too. Seemingly bigger than the holes, but he was on the floor so...
