The Puffer Forum

Hello everyone, quik question probably easy answered (hopefully) i got 2 green spotted puffers. Both in 55 gallon fish tank, they have been living together for years in that tank, but one is way fatter than the other. They both eat. The fat one is more dominant than the smaller, they both appear to be healthy and fine. Just concerned about the fatty one. Is it just becuase he is just dominant and eats more? He is probably almost double the size of the smaller one. Thankyou in advance,

Yes, the dominant fish will always get more food. They are best kept as a singleton in a tank that size.
