Review on 🐠 SZELAM 25W Smart Mini Aquarium Heater: Submersible Betta Fish Tank Thermostat for Efficient Water Temperature Control, Anti-Explosion & Energy-Saving Warmer by Heather Brown

We have a rooster and the pet store was surprisingly uninformative. When we realized the poor thing needed hot water we got scared and got this heater delivered the next day. We put it on, and it didn't heat the tank for a long time - at least not to the desired 78 degrees. In fact, it took a full 24 hours to get there, so we were very concerned. Now that it's reached that temperature I'll see if it stays more or less there, or if it gets too hot (I hope not!), but so far - so good. The device is very easy to install, the suction cups work great: while looking for a suitable place, one of the suction cups came loose, but it was very easy to put it back on and continue. The two plants (I thought there should be three?) are not very important but they are cute and my son was very happy to add "decorations" :) while my mother was wondering why they weren't green are - hahaha! In the picture we pasted it for the first time, and the temperature did not rise above 72 degrees for a long time. After further inquiries in the pet shop it turned out that the range of the fighting fish is 72 - 82 degrees anyway - well. In theory, it should have been comfortable since we put it in (actually, it walked and snuggled against this thing until the rest of the tank warmed up! poor fish.)
