Purchased on TikTokIt seems to work well. I wish I could adjust the temp. It came at 78° F but that’s fine for the shrimp I’m getting! I just hope it doesn’t overheat them. This is a small 1.5 gallon for scale

Description
Mini Size: The heater is 4.5" in length making it a great choice for small sized tanks from 3 to 5.5 gallons without taking up much space and obscuring the viewing area. Easy to Use: The small 25W aquarium heater is preset to 78?F which is a perfect temp for Betta and most of tropical fishes, and no setup needed just plug and play. Easy to Check: The indicator light turns red when it is heating and it turns green when it is resting so it is easier to do a quick check every day. Includes: 1x 25W Small Aquarium Heater, 1x Suction Cup, 1x Free Thermometer Strip Cautions: keep it fully submerged under water before plugged in, and unplug it and wait for at least 10 min before you do aquarium maintenance or take it of water.
