Aquarium Advice Apprentice
Hi everyone. Im not too familiar with fish diseases here with freshwater fish. My landlord has a 55 gallon tank and today when I was over there her tiger barbs (3 of 4) have their mouths open forming an "o" in which they cannot shut nor can they eat. I feel so bad for them. Any experience with this? What is it? Can anything be done now? ANY help appreciated. She said she does water changes sometimes (which probably isnt that often) and just tops off her freshwater. I personally think her tank is WAYYYYYYYYYYY over stocked, they must have about 50 some fish in there. So what can be done, I just feel so bad for them! Thank you for your help!
