Best heater for dishes with multiple temperature settings
I got this to match the tank brand that I have. the tank has a dedicated slot for the heater to go in, other wise u donโt want the heater to be exposed and hurting the fishes. It works very well, great value and easy to use with temperature adjustments. No noise or stickiness at all.

Wonderful!
Arrived safely, all in one piece. I use this in an 8 gallon shrimp tank, it keeps a consistent temperature and seems great so far!

Lasted 10 months only
I bought this 5/2/25 with the wonder tank, and it worked only for mid May 2025 until February 2026. Very disappointing to see that the water temp had dropped and find that the heater crapped out. I like that it fits in the tank and is not seen, so I just ordered a new one. Be aware though it doesnt last long.

Tropical fish survival
Tropical fish need warm waters to live since purchasing this heater Iโve not lost anymore fish and they seem to be more active.
