Agree and even longer if possible.. and if fish doesn't need to eat feeders then some other quality food is better..two to three weeks
Don't do it, they may say they are disease free but you can never tell.
Not only feeders are bad for your fish but they have no nutrients what so ever. Here are a few great things to feed carnivorous fish.
Tilapia
Silversides
Bass
Trout
Hikari Pellets
NLS pellets
Shrimp
Bloodworms
p.s what fish are you feeding?
Dont know about you, but i gave up on growing guppies real fast. It's take 3 months for them to be big enough to make a decent meal for my fish.
At first I thought I'd go to convicts, but they'd still be small for a while.
So I decided to breed talapia. Having problems finding female tilapia now.
I think I might just start breeding kittens for feeder fish.
