If you buy it small and don't keep it long, it might be okay. The mistake that a lot of people make in scenarios like this is that they say they will rehome it later, but they wait until the fish is already too large or health issues arise and then decide to rehome. IMO
, the damage has already been done and the fish will likely not do well in the new home. If you absolutely have to get one, get rid of it sooner than later.
had a huge Foxface last week too. Probably close to a foot long and thick body. I'm not sure I've ever seen one that large before.
