Has anyone tried keeping cherub angels (Centropyge argi) with seahorses? I've had my eye on a pair from seahorse savvy, which sells them as seahorse-safe tank mates, but I'm still a little wary. They would be kept with a pair of H. erectus in a 90 gallon reef with lots of rock and caves. Do you think it would be safer to get only 1, or should they be avoided all together?
