I'll get straight to the point, why only white fish fillets or tilapia when it comes to feeding fish to freshwater fish. Why not things such as trout? Why not oily fish? Why not feed saltwater to freshwater? I know that to my dog who is on a raw diet, offal is essential to her health, so surely by only feeding fillets and not at least supplementing with bits of offal are we not missing a key component of our fishes dietary requirements?

I feed my fish herring and cod all the time.
 
Fish fillets on there own aren't good for any species. Predatory fish eat whole fish, bones, organs, stomach content etc. Fillets need to be supplemented by a varied diet or vitamin supplements. Oily fish can be good as a treat but don't do much for the water quality.

When i buy herring it is a whole fish except the stomach and organs. Its fins, bones and head. But due to its fat an doil content i have to do major wc after feeding with it. If im feeding shrimp i feed whole shrimp with its shell and everything.
 
In nature when a fish eats a fish, it eats it all, guts (and the stuff that fish ate), bones, organs, etc, etc and gets complete nutrition, feeding only the fillets is incomplete nutrition unless you stuff that fillet with vitamin enriched pellets.
 
Agreed with the points of whole fish providing the most nutrition and to answer the posted question it's about convenience and economics.....fillet such as tilapia is easy to work with and cheap to buy in nice sized amounts.
I don't even use much raw fish of any kind these days but I'm certainly not going to be offering any messy or oily fish in my tank that might put extra stress on the filtration system.
 
Somebody (I won't mention the name) said this "What a fish does in nature, should never dictate what or how one feeds in captivity. "
Seems to be sort of a silly comment. I am more inclined to take into consideration what a fish eats in nature. Not suggesting we feed fish feeders. Just agreeing with Duanes. Everything should be considered.
 
All makes sense. I'm very glad of the helpful replies.
So in considering all this and the responses I got to thinking. As a fishmonger at a premium establishment I have access to a good range of seafood. How much on average would you spend feeding a quality diet, not including pellets or anything? Just I had an idea there might be a little gap in the market. I could put together a range of suitable seafood, like a good little variety enough to provide say two weeks food for the average predatory fishkeeper and post it out frozen to UK residents. Now obviously at this stage I'm just basing things on educated guess work but I reckon I could do a premium package like that for about £25-£30. My question is simple, is it a good idea? Not in terms of quitting my job and getting a mansion but could it be a workable little something on the side? I don't want anyone thinking I'm on here just trying to spam for business, there is no website for me to link, no business, just a little idea.

For that would be worth it. I usually feeds my fish with maybe 150-200gbp every month then pellets on that. But i live in sweden.

Ha-ha-ha-ha. Thanks for the laugh Dave, I have probably forgotten more about feeding fish in captivity than you will ever know. Just feed what your fish enjoy, you'll both be happier that way. lol


To the OP, have you looked into the regulations involving selling seafood via the mail, in the UK?
