TopFin Essentials 5-Gallon Betta Starter Kit
If you’re stepping into the world of fishkeeping for the first time, the TopFin Essentials 5-Gallon Betta Starter Kit is designed to make your journey seamless. This compact yet thoughtfully complete kit includes a crystal-clear glass tank, LED hood lighting that enhances your betta’s vivid colours, a gentle low-flow power filter that won’t toss your betta around, and a fully submersible adjustable heater to maintain the 76–82°F temperature range bettas need to thrive. Assembly is beginner-proof — most owners have water running within 30 minutes.
TopFin Essentials 10-Gallon Aquarium Starter Kit
The 10-gallon size is the sweet spot of beginner aquariums — big enough for a small community of fish, small enough to manage easily — and the TopFin Essentials 10-Gallon Starter Kit is the definitive entry in this category. The kit bundles a full-size glass aquarium with a fluorescent hood complete with bulbs, a Top Fin Power Filter 10 loaded with a cartridge, a 50-watt adjustable UL-rated heater, a 4-inch nylon net, a strip thermometer, and sample sachets of fish food, water conditioner, and beneficial bacteria starter.
TopFin Captivate 20-Gallon Aquarium Starter Kit
For aquarists ready to step up from a nano setup, the TopFin Captivate 20-Gallon Starter Kit is an ideal upgrade that unlocks a whole new world of aquascaping possibilities. A 20-gallon tank provides significantly more swimming space for larger species, larger community groups, and the kind of lush planted scapes you see on social media. This kit includes the 24″ × 12″ × 20″ glass aquarium, a full 24-inch fluorescent hood with light, a Top Fin Power Filter 20 with cartridge, a 100-watt adjustable heater, a strip thermometer, fish net, and the usual sample packs for water care. The 100W heater is rated for tanks up to 20 gallons
What pets say about our shop
Clients Testimonials
My betta Sapphire went from looking lethargic in a tiny bowl to absolutely thriving in the TopFin 5-gallon kit. Within two days his colours had intensified noticeably and he started building bubble nests — a clear sign of a happy, healthy betta. The filter is gentle and the heater holds exactly 78°F. I’m obsessed.
Glen Sparkle, MIAMI
I upgraded from a branded competitor’s filter to the TopFin SilentStream and the difference was immediate — crystal clear water within 36 hours and near-total silence. I work from home and used to be constantly aware of the filter noise. Now I sometimes check if it’s even running. 10 out of 10.
Glenda Richards, CALIFORNIA
The 10-gallon starter kit was the perfect choice for my first community tank. Had it cycling and running within 45 minutes, fish in after a week. The instructions were remarkably clear and the included water care samples were genuinely useful. Six months later, my neon tetras and corydoras are thriving.
