Review: Working great so far. - I have a smaller 5 gal aquarium I was planning to set up for two male bettas. I haven't got the bettas yet, they are due to arrive this Tuesday. But so I have a glo fish, 2 ghost shrimp, 2 algae eaters, 2 snails and a couple of aquatic plants. This product has been great at keeping firmly stationary in the center of my tank. I had to do some cutting to modify it to fit, but it was not difficult to do at all. I have a small gap at the top of one end of the divider, but so far it has been great at keeping the glo fish and the ghost shrimp on their prospective sides of the tank. The snails and algae eaters have been able to sneak back and forth to each side of the tank which I have no issues with. I have read some of the others reviews about using this for bettas, so I am a little leery how well my two bettas will do once they are let loose in this aquarium. I am hoping they will not be over stressed with being able to see through the divider. But just in case, tomorrow I am heading to purchase a 25 gal aquarium I had already planned to purchase. So if they get to stressed, I will just move them to the larger aquarium and use this or another like product to separate them. Review: Impossible install, falls apart in use - It was a pain to install, but once it was installed, it seemed to work okay.... for about 3 months... then it began to DISINTIGRATE!!! Big tears and holes seemed to appear overnight! I had to scramble to order a clear plastic divider (next day delivery!) Before I had dead fish!! It's definitely NOT worth the money OR the time it takes to struggle with the install!! ## Features - Divide with Ease - Instantly transforms one aquarium into two sections, offering flexibility for multiple fish setups while keeping each area safe and separated. - Breeding Made Simple - Creates a protected area for breeding fish and baby fry, helping reduce stress and keeping new life safe from larger or aggressive tank mates. - Peaceful Coexistence - Helps control aggression by separating territorial or β€œrough” fish, maintaining harmony while keeping your aquarium healthy and balanced. - Sized to Fit - Designed for 25–29 gallon aquariums and measures 11 3/8” x 17 1/2”. The perforated panel allows natural water flow, filtration, and heating circulation. - Passion for Aquatics - With decades of experience, Penn-Plax creates reliable aquarium accessories that support healthier, safer, and more enjoyable fishkeeping for hobbyists of all levels. ## Technical Specifications | Specification | Value | |---------------|-------| | Customer Reviews | 3.7 out of 5 stars 1,207 Reviews | ## Product Details - **Brand:** Penn-Plax - **Material:** Plastic - **Tank Volume:** 27 Gallons - **Special Feature:** Lightweight - **Shape:** Rectangular - **Specific Uses For Product:** Indoor - **Style:** Modern - **Color:** Clear/Blue - **Included Components:** Penn-Plax 54501427: Tank Divider, Super 29-55G - **UPC:** 030172014277 738759908833 ## Images ![Aqua Life Tank Divider - Super Size Aquarium Separator - Instantly Converts One Tank into Two, Easy Setup for Fish Breeding, Isolation, Aggression Control & Water Flow 11 3/8 x 17 1/2 Inches - Image 1](https://m.media-amazon.com/images/I/71EAZDqPMWL.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Working great so far. *by C***5 on April 7, 2012* I have a smaller 5 gal aquarium I was planning to set up for two male bettas.

We have an Oscar on 2/3 of the tank and guppies, shrimp, and tetras on the other 1/3. This divider is sturdy enough (it is a plastic material NOT mesh) to hold back our hungry oscar, while still allowing flow from one side of the tank to the other. We have an external canister filter, so our input on one end of the tank and our output on the other. I haven't noticed any build up of debris on the divider. I was afraid our 3-d rock background would cause an issue, but the divider just bows a little in the middle which is fine. The only issue is that it could've been just a few inches taller. Luckily we have a lot of sediment so that it can fill in the gap at the bottom. I just have to watch my fish and make sure they don't burrow under it. I do wish that is wasn't bright blue.... We strive to make our tank very natural. We have aragonite sand, mopani driftwood, live plants, and a 3-d rock background, so the bright blue tank divider kind of takes away from that. Overall, a great buy for the price! ## Frequently Bought Together - Penn-Plax Penn Plax Aquarium Super Tank Divider - PENN-PLAX Fish Tank Divider – Clear, Perforated Polymer Screen – 11 3/8” x 9 5/8” – Medium – Great for 10 Gallon Aquariums --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/3926842-aqua-life-tank-divider-super-size-aquarium-separator-instantly-converts](https://www.desertcart.us/products/3926842-aqua-life-tank-divider-super-size-aquarium-separator-instantly-converts) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-09-28*
