help fish start dying

[Madreefer]

First off I'm not trying to be a dick. I'm just straight up. Seriously dude, you really have to find a better store with a knowledgeable staff. Impulse livestock purchases are detrimental in alot of cases without ALOT of research. Doing your research and having patience is really rewarding in this hobby. Listen to the advice people on here are offering you. If you don't trust the answer than research some more. Don't be like me and learn by trial and error and trusting that person selling you whatever. It's discouraging and costly. Stick to reputable specialty stores.
