Fish Fanatic
I went to bed last night and my tank was the same as ever, I got up this morning and there are bubbles all over the top of my tank. In the corner opposite it looked like a bubblenest that a betta makes. However I don't have a Betta to have done this. I currently have 6 copper rasboras and 3 black khuli loaches. I haven't added any chemicals or medications to the tank, pH is 7.2, nitrate is 20 (due a water change tomorrow) ammonia and nitrite are 0. I may have been overfeeding slightly to make sure my new khulies get some food, but even when I cycled with fishfood I didn't get bubbles like this! I'm stumped. Any ideas anyone?
