I visited my local pet store and saw bamboo shrimp for sale. I had read about other shrimp and how to take care of them and I had an empty 10 gallon tank at home. I had no idea that they had way larger tank size requirements. I was really quite sure that a couple would be fine, but I did a quick search just to be safe. The first few results all said 10 gallon as the minimum, and so did the store employee. I bought 2 and took them home. When I got home I did a little more research and found that the recommendation was 10 gallon as the absolute minimum for just 1, and that 20 was really more suitable. I am now absolutely freaking out because I don't know what do do with them. I bought plenty of food and the tank seems otherwise suited for them. I just need to know if there's any chance they'll be alright if I feed them often, and if not what do I do? Do most pet store's allow returns on the basis of having made a personal error, I'd assume not. I don't know anyone with a fish tank and I really just want them to be safe and happy. Please, please let me know if there's anything I can do so that the shrimp don't have to suffer for my stupid mistake.
