Snoop's Take

The Penn-Plax Aquarium Super Tank Divider is designed to create separate spaces within 25-29 gallon aquariums, allowing for tailored fit in both freshwater and marine habitats. Its unique slide plastic "Flo-Through" design ensures crystal clear visibility while keeping aquatic pets safely separated. However, feedback indicates potential downsides, with users noting that it can lead to persistent aggression between fish, as one comment mentions, "it’s dangerous I have seen people do this and there fish has jumped over and attacked the other one." Despite its versatility for breeding or isolating fish, caution is advised when using this product in aggressive species setups. The product is a practical solution for aquarium enthusiasts looking to manage different species or create appealing sections within their tanks. However, given the feedback surrounding aggression issues, it may not be suitable for all aquarium setups, particularly those with aggressive fish species. Overall, while the Penn-Plax Aquarium Super Tank Divider offers innovative features, potential users should weigh the risks of fish aggression before purchase.
