Here is the sentence:

Spiders that bite, hissing snakes, and squealing rodents fill the aquariums in Desmond’s basement.

When you list grammatical items, you must use parallel structure. Here, hissing snakes and squealing rodents are two nouns modified with participles, but spiders that bite is a noun modified with an adjective clause, which wrecks the parallelism. Nice choice!

To fix the sentence, change spiders that bite to biting spiders.
