im setting up a 75g tank and im throwing around stocking ideas. i have a 5" senegal and del waiting to go in my 55g. im thinking of throwing them in my 75g with 3 dats, range from 3-4". if i put them in the 75g id prolly get a palmas and another del and doing an oddball type tank. what else if anything could i or should i add to the tank?
