Hello guys, I’m a little confused as to what this “bug” is and if I can get rid of it. I’ve had a 3.5 gallon tank with filter and heater for a betta fish with a mystery snail. I’ve had the tank up and running since October 2020 and have had no issues until recently. I went to introduce a new snail about a month or so ago and it didn’t look too hot when I got it so I figured it wasn’t going to last too long. Around the time it died I started noticing these small bugs. They would just float around and would be in my filter. So I would empty the filter to make sure they wouldn’t be in my tank. I did have three small moss balls in my tank but after noticing some debris or even egg looking stuff on the moss balls I decided to take them out and throw them away. After asking someone at petsmart what they could be and then telling me they have no idea I come to you guys. I’ve cleaned my tank down to literally a 90% water change as well as changed the filters and gravel and they are still there. My betta is slowly dying since I’ve gotten these things. Please help!!!!! *** the attached pictures are ones I’ve scooped out of my filter and are “dead. They seem to be clear when they are alive and in the water.
