I have an empty 10 gallon tank all cycle and ready to go. I want to try something challenging. I am ready for it. I am open to any and all suggestions and then I'll turn it into a poll. I have larger tanks so if it did outgrow the ten it would have a happy tank to go to. Fresh, brackish, or salt, it doesn't matter, please give me some ideas.
