oh my jeezus. Aparently my guys are starving...mind you, my biggest is my 14 inch rtc..so maybe not. Every 2nd or 3rd day the cat-pond(6x4x2) (14 inch rtc, 2x13inch lelarius longibarbus, 10 inche tsn) get a handful or so of massivore, 2 cups seafood medley or shrimp and as a snack some talapia (only really when I buy hallibut for the hubby and I to eat)
