Yesterday a line of bubbles appeared around the rim of my tank...it looks very similar to the bubblenests made by bettas and gouramis..
I have a 55 gallon with 4 goldfish- 2 fully grown orandas, 1 3in moor, and 1 3in oranda (who is currently in our hospital tank), 1 dojo loach, 3 mystery snails, 1 cory cat, 1 bristlenose pleco, and 1 clown pleco. We do a 33% water change weekly.
Any ideas?
