Reddit reviews JW Pet Company Smart Temp Standing Thermometer Aquarium Accessory

It's very kind of you to not just let him die! If you get him spiffed up you may be able to find someone who likes fish to take him in, so you don't end up feeling burdened...

but in the meanwhile, there is some basic stuff you can do. If your measurements are correct, then he's probably in a 2 1/2 or 3 gallon aquarium, which while not the best, will certainly suffice. This means the main things you'll need are a filter and a heater.

It would also be nice if you got him some stuff to hide in, so he doesn't stress. They make aquarium decorations, but a clean, well rinsed ceramic coffee mug or unpainted terra cotta planter will do the trick for cheap.

By the way, can you post the name of the water conditioner that you found in the tube? It will help me be able to figure out if it's a dechlorinator or not, which is the most important thing.

Also, does the tank have a lid? Bettas will jump out of water, especially if the water quality is bad.

Anyway, there is plenty of inexpsensive, decent equipment for a tank that size:

I personally happen to like this filter for a tank that size, and it's very easy to install/maintain.

Here's a nice little heater that's worked very well for me. You'd want to maintain his water between 75 and 80 degrees, so it's always a good idea to have a thermometer to make sure the heater is doing its job properly.

From there, maintenance is pretty easy. Feed him just 3 or so of those little food pebbles a day, and once a week give him some of the bloodworms for variety. The main thing is to not overfeed, because they have very small tummies.

Once a week, change out about 25% of his water, and rinse out your filter pads with old aquarium water if they need it. They make little syphons especially for this, because the suction they create helps you vacuum poo out of the substrate.
