Hi guys, i love doing this and i can't stop myself doing it. To give fish more nutritions than what they absorb from food, is it safe to add crushed multi vitamins or crushed spirulina tablets into the water?
when i mix with frozen jumbo shrimp, second morning it became too hard, and when i mix with krills, it decays or became stinks. Do you have any ideas? should you paste powder form of vitamins onto shrimps or slice it into paste and then microwave it?
Get a tablet and pound it to powder form. Slice the large shrimps and stuff the powder in them. When done, feed them straight to the fish. Pasting will still dislodge some of the powder once soaked. Your other option really is just make gel foods and combine the multivitamins with them.
