Although I think that many insects are just 6-legged aquarium fishes, most people obviously do not agree with me. Since you are probably quite experienced on dealing with such things, I would be glad to hear your opinion on the matter.
I do not agree, since insects and fish are each in their own phylum of classification. Fish are vertebrates while insects are invertebrates. Maybe you are trying to make an analogy, but if so I am not sure it is very logical.
