My work gets it from the same place we get fish from, which carries most types of NLS. You can get other types online if your LFS isn't carrying it, or ask them to get it in for you (although online would probably be cheaper). I give my 150 and 40 the Large Fish (3mm sinking). The 75 and 40breeder get Jumbo (4.5mm floating, sometimes listed as 5mm). The 40breeder also gets the jumbo Thera A (6mm sinking) to help fill up the axolotls. I also have the water stable algae wafers for the pleco in the 75.
One of the nice things about this food is that since the formula changes so little (if at all) from one variety to another, you cna focus on what siize you need andd whether it floats or sinks, not whether it says goldfish or cichlid on the bottle. It sounds so backwards, but this somehow really does provide the best diet for all these fish.
How big is your EBJD?
