I've actually got a 65, and it's the only trigger in the tank. Does 5 gallons make a huge difference? I've got a sump & fuge attached to it, and am thinking about making the sump bigger to allow for more water volume (since I'm not currently in the position to buy a new tank)
Will he be okay long term in this size tank? I've got 3 small fish in there with him (2 damsels less about 1" each, and a green chromis), and a Juvi Koran Angel - which long term I NOW understand should be in a larger tank (I know, I know - I should have done better research before taking him in!).
