I was able to buy a multivitamin tab for fish, its azoo Multitabs, which is dropped into tank and will dissolve automatically, I was wondering if this can split into 4-5 pcs and inserted into food for my arowanas? the tab is effervescent, not sure if this will have a bad effect? when i dropped a tab into my tab, 1 of my arowanas ate the tab and kept chewing on it before spitting it back out.
