If you're fish are fine feeding terrestrial vegetation than have at it bro -- and same if you want to feed Tetra anything, which most people in the know think is crap fish food overall. But you've been doing this for years as you say, so I'm sure you know better lol, each to his own.
And yes lots of commercial fish foods, even Hikari use terrestrial based plants, that's because basically they're cheapos compared to the companies that don't (like NLS). And there's certainly a difference in using such ingredients in a pellet vs. cut up and tossed into your tank to get torn up (would love to see how that affects your water quality), but each to his own.
Also I'm not saying feeding fresh land-based plants is going to kill your fish (unless maybe if you don't remove 100% of the pesticides they put on most veggies nowadays) -- what I'm saying if you'd get past your sensitivity and read more carefully, is that it's
absolutely not necessary with a Flowerhorn (and I would argue the same for frozen foods and krill), but each to his own.
I don't have a problem with fish food lying around the bottom of my tank, I only feed in measured amounts and my fish eat the food soon as it hits water or lands on the bottom. Then I give some more. So I don't have to worry about vitamins and such leaching out beforehand. But if you don't believe the premise of what I'm saying, then up to you, each to his own.
Lol if you want to put it that way, when talking about Flowerhorn -- which you've kept how many?? -- you're exactly right, I am suggesting your fish keeping advice is inferior, but I certainly wasn't aiming to make you feel inferior, sorry about that. If you want to be so sensitive you cannot accept anyone offering a different and very arguably better way of fish keeping -- while you come on here acting like a Flowerhorn expert -- that's up to you, and sorry I don't really care if you resent the implication. There are some who powder-puff their responses on MFK, and there are some who don't -- you will run into both types here, just like in real life.
And it's called learning bro, and all of us with open minds benefit from it. Is this site now being overrun by Snowflakes?!? If so that's very sad because for sure it will stifle the exchange of information and learning process many of us come here for -- even if we may run into different, even opposing views.
If you really want to learn more about proper diets for fish Sir, I humbly suggest you peruse some of
RD.
's posts in the Stickies of Cichlid and Flowerhorn sub-forums, it'll open your eyes about the how 'good' your practices are before you go around advising others to do the same.
