I'm fairly new to the world of fishkeeping, especially cory cats since growing up I only ever had betta or goldfish. So I'm just looking for more information.
Well now I have two albino cory cats in a 10 gal
tank (I plan on getting a couple more). Originally I had my betta in the tank with them but she got sick and is currently in a quarantine tank. There were always bubbles built up on the water surface and I assumed they were the doing of my betta. But I've removed her from the 10 gal
and have done a full cleaning of it and the bubbles are back. They are even stuck to the underside of a couple (fake) plant leaves under the water.
Do corys blow or release bubbles that do this? I'm assuming they aren't the sign of anything harmful since they are just bubbles. Thanks in advance!
