So my betta, Bob Buttons, always greets me & comes when I call him. Today he is acting depressed - just hanging out in one corner & not paying any attention to me when I talk to him, etc. When he does finally leave that one corner, he is swimming much slower and acting more lethargic than normal. He doesn't seem injured or bloated, and I can't see anything physically wrong with his body. He ate this morning, and is still taking occasional breaths from the surface, but something is definitely not right. I'm not sure what is wrong & I'm really worried. Any advice would be helpful! Thank you!

two tips i can give you at the moment would be to invest in a water testing kit, i think i got mine for around 25 dollars at petco. its very important to know what your water parameters are at because they can help or hurt your fish if they are too high or low . very important. and secondly I would change how you do water changes a little, i dont know about other users , and this is just my way of doing it, but i dont let water evaporate very low befor i change my water. i do a 25% water change twice a week. ill sucktion about 25 percent of the water out and then replace what evaporated and the 25 percent I took out , with new fresh water. I have a 5 gallon bucket i got from homedepot with a heater set to my tanks temp and air stone in it that i keep filled all the time, so when i need to do a water change i have fresh water already prepared and ready. I hope your fish bounces back and gets better and i hope you find out what is bothering him
I just want to add to Sassy's advice by saying, rehome those algae eaters. No catfish are suitable for a 5 gallon tank and they will not stay small for long. They are (most likely):
- plecos, which get between 6 and 24 inches depending on species and hav a huge bioload
- otos, which are delicate little things needing groups of 5 or more
- Chinese Algae Eaters, which get huge and very aggressive as they age
- Siamese Algae Eaters, which need at least a 20 gallon tank, getting about 6 inches long and very active
Sounds as if he is having issues with the chemistry..
You don't need to have the water sit out if you wish not to, but it's highly recommended to use tap water + conditioner over filtered water- as filtered water tends to lack needed minerals for the fish.
For 5 gallons, filtered, no live plants 30-50% water change per week with weekly gravel siphoning is needed to keep the water healthy.
