You should bring your guppy carcasses back to the store that sold you the shark
Another example of the LFS either being ignorant or flat out lying to make a sale. As previously mentioned red-tail sharks can be incredibly aggressive when they get bigger. I was at a chain store one time looking at fish when I overheard a customer returning one that had killed half his tank. He was angry because the previous salesperson had told him they were only aggressive with other red-tailed sharks. The young lady that processed the return was clearly no fish expert because she placed the shark in a tank with a bunch of juvenile balloon mollies. Before I could say anything it swallowed one hole and had started nipping on a second. She fished it out so quickly she almost tossed it on the floor. I no longer ever trust LFS or anyone who stands to profit from selling me fish or dry goods. I finally found a LFS that I pretty much trust but only by going to half a dozen and being given either bad advice or outright lied to.
