Some friends and I were making sushi, and we were left with a sizeable quantity of Sweetfish Roe. I figured why let it go to waste, and figured I'd try feeding it to some four month old cichlid fry... They go NUTS over it. I tried it with my croaking gouramis and tetras. Same result- even though it sinks fast, they frenzy over it. I've only been doing this for about two days... but can anyone see any downside to using saltwater fish eggs as a fish food? They seem to be a real crowdpleaser, and since it was $2 for an enormous quantity of the stuff at the local korean grocer, it was substantially cheaper than most any other live foods I've found out there, and I'd imagine it's good nutrition as well. I've read on sites that when frozen, it can keep for three months. has anyone tried this or heard anything about this?
