Zoo York, that is a Takifugu Obscurus Puffer. And Ewurm, I thought you might like them. You were actually part of the inspiration to buy the loach lot. They are going in another 250 gallon soon.
Thank you, its hard to take pics of the loaches without a flash, they dont like bright light over their tank so pics come out a little on the poor quality side. But I will work on it.
