2 Pack Fish Tank Divider with Suction Cup, Aquarium Divider Plastic Cuttable Grid Plate for Juvenile Fish Separator DIY Designed Clear Easy to Bent Cut and Assemble, 13x17.3in

So we decided to buy another fish against PetSmart warning. Two betta fish cannot be together. I decided, well, if I buy a divider then they can both be in there own sides if the aquarium. WRONG! One fish immediately was trying to get on the other side. Kept looking for ways to push through. Then, the other fish pushed through. I was shocked. They seem to just be following each other around. I went to take a shower and send some emails out. By the time I went back to check on the fish, both were dead!! My son was so upset. It was my fault. I should have not even tried to put them together. I honestly wish I stayed and watched what happened but it is well. We bought one goldfish today so my son is good but please don’t try this with beta fishes. I still can’t believe how fast they died.

I purchased this product to divider my tank for two Betta fish. If I could get my money back I would but Ive already cut both sheets the first one was to short, so I had you use the other sheet and cut it larger but that didnt work or help. The issues 1. The suction cups do not stick and the clips werent really functional, you attach it to the screen they fall right back off. 2. The product bows and does not stand straight up. 3. Not Secure, I Looked away for maybe 10 minutes and the one Betta squoze right on past the divider on the side. I caught him as he was seeking out my other fish. I do not recommend this product.

It kept my tank divided but my crayfish ended up climbing up, pushing out of the completely closed tank and died .

Update: I bought report cover binders and put it on all four sides and it worked perfect! Installed this in 2 different 10 gallon tanks and once the suction cups go on after trimming it leaves a gap. Fish have to be pretty good sized for this to work. I wanted to separate some older fry and they still managed to swim through even if suction cups were on one side and none on the other side. The side without the suction cups had no gap and the side with the suction cups had a gap. I don’t recommend for smaller fish for sure! Not happy with the outcome.

I had a juvenile tiger barb that was being aggressive to my bottom fish all of a sudden and needed to separate them asap. This was quick to install, stayed in place, affordable, and gave me time to find the barb a home

so so

Just letting yall know this is a terrible overpriced product. The suction cups have nothing to fasten them to the plastic divider. When I tried to use it, it literally fell over just with its own weight. This is unusable. I ended up returning it and buying a better quality product. This is a prime example of cheap overpriced stuff

Tank dividers in general, have always been a pain, and these are no exception. It’s a bit tricky to get in place without losing a suction cup or 2 or 3…lol….soooo, after the 3rd or 4th time retrieving your lost cups and sharing a few choice words, it’ll come together..lol. The material seems a bit flimsy, but cuts easily with scissors. Once you actually manage to get it in place, straight, and suction cups in place, it appears to be adequate. I am splitting a 55 due to 2 different breeding pairs of cichlids. For the low cost, these seem to work fine. Time will tell if the suction cups hold up. Be sure to account for the suction cups when you measure. Check and double check. Once you cut too short, yer screwed…lol…don’t rush…especially since this material cuts so easily.

This was not a very useful product. I tried to install it in my tank but it didn't work as I was hoping it to. Fish could move around it.
