I am getting ready to start my project of biulding my own tank. its going to be a plywood tank with a acrlyic front. I have right now 260watt of lighting. and my LFS told me 260watt would be good for anything except coral on a tank up to 100 gallon. So my tank size goal is 50-100gallon, The fish i was are a humu trigger, any type of eel, any type of lion fish, and maybe something else compatible. the gentlemen at the LFS told me i wouldnt need any type of skimmer or overflow tanks/sumps. So my questions are, What size tank should i biuld for the fish listed, Sense i'll be buying them fairly small( no more then 3'' each) i dont expect to need a huge tank, and what size filter should i look into? brand names and such . Any info is apreciated, thank you
