Dog faced puffer

[Jlemayy]

I got a 20 gallon tank. Just got a dog faced puffer in there by himself thinking of adding 1 more fish what would be a good match to keep in there with him.

I dont know if you know this but that fish needs a minimum 150 gallon tank so i dont know your plans but that certainly needs to be addressed

You have 2 options. Buy a 150+ gallon aquarium and start cycling yesterday, or return the puffer to your local fish store and try to get some credit towards a pair of clownfish. Even the smallest dogface is going to eat a ton of meaty high protein foods. This will foul the water very rapidly and nothing happy or fun will come of it.
