You'll need to lower it at least 5 to 6 inches then.

Do you know how insane this is?!! That would mean a male betta could easily clear the tank partitions (with plenty of hangtime)! :lol:

Please note, long finned males VS females or PLAKATS will always vary. My females can jump very well. One of my fry eluded the net, cup, ladle, by jumping pretty dang high - and she is only 7 weeks!

However none of my males get their full body out of the water.

Find some nice acrylic, drill holes in it and perhaps make a feeding hole by remount a piece and attaching it via hinge. Keeps it clean and clear looking without a bulky hood, but that way you won't worry. I don't have lids on my male's tanks. But I also know my fish individually - and which ones are trouble makers (aka failed wannabe elvolutioners :lol

I like the using the Mesh Ideas.

Floating plants do not stop females, especially if it is feeding time.

My girls don't go for height, they go for length. I have one girl who went through this weird phase where she would jump and stick to the wall of the tank briefly.

Floating objects certainly don't stop my girl from jumping.

Well, to summarize: it varies from betta to betta on how high they may jump. If you get to know your fish and their behaviors first, then you will know the appropriate course of action.
Until then, lower the water approx 2-4 inches and go from there.

Also, post pictures of your tank please! I love rimless tanks. <3

:lol: Mine did that. One would actually get my attention by jumping out against the glass, sticking, plopping back in the water. And repeat.

I expect much of that tonight. I just bought frozen brine shrimp.

Here you go....enjoy. BTW the water is about 1.5 inches from the rim top in these pics.

Depens on how many floating plants and what kind.

 

[xjenuhfur]

Oh it looks so good so far!!
I can't wait to see once you get more plants and stuff in there.

Ive never measured it but estimated it appears my water level to top of lid is about 6-7" and I can hear my plakat smack of the top of the lid when he spooks...id say he could probably go a little higher too, however my long finned double tail can barely get out of his own way let alone jump...guess depends on the fish and the type of fish. I dont think id ever be able to trust my plakat without a lid.

One solution would be is to go to a small hardware store (Ace, TruValue) and ask them to cut a piece of hardware cloth. They'll show you the different mesh sizes it comes in. 1/4 inch should be best. If it's cut just right, you can place it on the rim of the tank and you shouldn't be able to see it. It is rigid enough not to sag, like I think plastic canvas would. I'd use some clear packing tape along the back to make a "hinged" lid for feeding. Hardware cloth is to heavy for those eager beavers to lift (while they could bust through plastic canvas). I've learned what clever, determined little monkeys these fish are! Plus, anything for a snack!!

P. S. Home Depot, Lowes will not custom cut a piece of hardware cloth for you. If (and when) the help there figures out what hardware cloth is, they are more than happy to sell you a roll 40' by 12'. Only the small stores will cut it to fit your fish tank. Plus, I don't think the piece you buy will cost over $1. If you want to go the extra mile, paint it with some white spray paint made for outdoor metal.
I know about this b/c as a child in the 60s-70s, my Mom decided to raise a shoal of swordtails. Talk about jumpers! She bought a $7 fish (lovely b/w speckled one) and it jumped into a waiting cat's mouth! Another jumped into her handbag- she didn't notice it until it was waaaay too late :0( After these 2 incidents she used the hardware cloth with a large rock on it for good measure. (That was a $7 fish in 1972 prices. She was not pleased with the cat. But, what's a kitty gonna do?)
