A term present in the online fishkeeping community to define commenters that call out the shortcomings of the original poster’s fish husbandry.
In most instances, the critiques brought forward by the “fish police” are correct. However, the negative connotation likely stems from the fact that most of these commenters are likely teenagers whose method of delivery can be seen as unnecessarily aggressive. Factoring in ageist attitudes, nobody likes to be lectured about anything from an account that is obviously being run by a minor.
