So this is pretty much the nicest tank divider on Amazon, at least that I saw. It looks professional. Much nicer than those plastic square or mesh ones they sell for less money. This will make your tank look much nicer, and well worth the money in my opinion. I have the 20 gallon long, and because of this divider (fits absolutely perfectly), my Betta has a bigger and better living space. He’s roommates on the other side are guppies who previously took up the whole tan (I know there are too many guppies, I’m bringing half to the fish store this week) This makes me want to buy more 20 gallon long tanks and make them into three 6.33 gallons or split 10’s ... show more

    • It fits 20’ long aquarium tank
Size: 20gal Long Aqueon
I love it! Does what it’s supposed to, divide. At the moment pretty happy with my purchase, easy to install. Most importantly the size fits. I purchased it for a 20’ long tank aquarium it was one of the options and the size I was looking for to fit.

Very sturdy, about as thick as the tank wall. Fits my 20g long nicely but my nano fish can get through the side cut outs along the edges. By nano, I mean Scarlet Badis and Sparkling gourami. I bought two different dividers to compare. (I included front and side pics of each) The other is quite thin, flexible and lacks the side cut outs so no one gets through. While I much prefer the quality of this divider, the other is more effective than this one. Unless I can figure out how to close that gap without it being unsightly, I’ll probably return it. Wish there was a clear piece that could be added like a puzzle piece to that gap. ... show more

    • Nice fit!
Size: 20gal Long Aqueon
Works great! Just make sure you measure the width of your tank for the snuggest fit. The protective film is hard to take off but other than that it’s a great product!!

    • Young fry can fit threw. But not the adults. Perfect divider
Size: 20gal Long Aqueon
Small fry obviously, and also small juvenile fish can fit threw the gaps on the sides. But it keeps adults in. Very pleased with this tank divider. I put mine in upside down. So the small snails can fit threw. The vent gaps. Not worried about the small fish due to the size of the fry. I got this to keep my albino Koi guppies separated from my fancy males. ... show more
