I am new at keeping fish. I have my first beta. Blue and red male, since November 2015. He has lasted a lot longer than I ever thought, being so new at this aquarium stuff. My gf got me interested in this as she has owned many betas and other fish in 2 large aquariums. My beta is now very sick lying on the bottom of the tank. I did a 75%water change today and added extra salt as he has fin rot. Will do another water change 100% the next few days with extra salt and hopefully that will help. But then I am flying out to Victoria for a few days, my boyfriend will be feeding my beta. He knows nothing about fish. I can't trust him. I know I have been leaving the light on too long thus algae formed. Silk plants only. Do I add big als multi purpose bio support?
Going there in 2 days to get new carbon. Thanks.
