I wanted to share my 2 betta tools I have made over the years. If you would like I can get a picture and try and post it on the site.
My first problem was catching my bettas, I heard that nets were bad (now I am not as afraid of nets) so I needed a quick way to catch bettas for various reasons when I had a larger tank. Betta are curious. If they don't see this makeshift betta catcher very often, they will want to look inside it and usually they will swim in on their own!
1 Betta Hex ( small hexagon shaped betta house) other shapes may work too but the hexagon one would get lodged in the tool very well
1 General aquarium net with an opening that is almost big enough for the betta hex.
What I would do is cut the net out of the net and bend the net shape around the betta hex. I would only place it near the back edge. You can use the handle to hold the hex in the water to catch the betta, pop the lid of the hex on, take it out of the water and the net easily slips off the bottom of the hex and voila, betta is caught!
Betta Syphon - Cheap, Small, Low flow rate, Easy to set up!
1 Length of aquarium tubing, I like the really flexable kind, the blue one.
(this should be long enough to run the entire length of a turkey baster as well as extra to run into your bucket, about a metre I guess.
1 Turkey baster from the dollar store, with a rubber top
Take the turkey baster and a pair of scissors. Open the pair of scissors so there are two ends. Use one to poke a hole right in the top of the turkey baster (be careful!) it will look like the tubing will not fit in but it does. Shove one end of the aquarium tubing into the hole you made in the turkey baster. Push the tubing all the way through till it is almost at the bottom of the turkey baster at the opening. There is your tool
To use the syphon (which is great for almost any size tank I made it for a 1 gallon but use it for my 5 gallon) place the syphon in your tank. have the other end of the hose in a bucket. Do your best to make the bucket lower than the aquarium so the water will use gravity to flow. Squeeze the turkey baster, sometimes you have to do it a few times but it will start to suck the water up through the baster and into the hose, sometimes it helps to hold the turkey baster in the squeezed position to get the water to flow. Once it does you can move the baster around the tank It picks up all kinds of debris as well as pellets that have fallen. It works great to drain your tank too. Another good thing is mr or mrs betta cannot get stuck in the bottom of the turkey baster, and unlike just a turkey baster without the tube you don't have to keep taking it out of the tank, you can just move around and vaccume your betta's house!
Please share your hand betta tools or if you have a better version of my tools I would love to hear about your modification!
