Hey all! I have a dog-faced puffer in a 125 gallon aquarium and am looking to buy some cleaners. They are doing a big order with my reef club so I figured I would get some. Out of these cleaners, which would be safe or somewhat safe from my puffer? I could get blue, red, or emerald crabs. I can also get sea cucumbers and then of course large white cerith snails, turbo/astera snails, and regular cerith snails. Will any of these work and if so how many would be good for a 125 gallon?
