JZMYXA First Impressions

"So I tried and tried."

Look closely at the slight taper in the connections to see which way to insert them. The fry didn't understand so they swam through the sides. I had ordered 3 others before this one. Very good divider for my 20 gal long freshwater aquarium. You can also cut it down to the size of your tank, which was not too difficult to do. I know Betta fish are aggressive, so they must be separated. And now I know they are getting enough to eat.

"I highly recommend!"

It was a bit too wide for my tank, so I cut it a bit and it's perfect. It dose have good flow between the tanks. Holes are drilled evenly and it will divide fish 1. I'm separating male and female cichlids. There were scratches when we got this so I originally gave it one star review. I had an oddly aggressive Molly and this worked great for the time I needed to use. And if you fill your tank very full with water they can swim over the divider.

"Love this seat cover."

They look like the edging that's on the tanks, so it's as attractive as possible. And now I know they are getting enough to eat. It was slightly long so I had to trim off the bottom edge to make it fit. No matter what size betta I put I know it won't go through the divider. And since it has been working ok, I decided to change the review to 4 star. It keeps the boys from being able to see each other. Divider works well for our two Bettas that share a 10 gallon aquarium.

"But it keeps adults in."

Make sure to set it up in the middle of the water pump. Very few problems just a couple things to keep in mind when buying. There are slots along the top that they can see through.
