mr.maroonsalty, I was admiring your two in the "favorite pairs and trios" thread which is what got me back on the Tilefish kick.
How many can be mixed from different species? I saw where krkqm2008 mentioned having several Tilefish from various species, but I couldn't tell from the comment if they were kept at the same time and in the same aquarium. If one were to have two pairs of two species, would there be fighting, would they school or would each pair stay together and ignore the other pair? If it could work, what would be the minimum tank size for two pairs?
FWIW, I plan on trying one pair in my 210 mixed reef but curious about that aspect of Tilefish.
