There are lots of overated fish. Lots of overated fish can get to golioth sizes but ussaly do not get as big as people say. Lets take doviis for example, A few people have monster doviis so everyone thinks that they need monster tanks. At the same time it is hard to fine doviis over 16-18 inches on youtube. most fish do not have the genetics to become way bigger than normal. Than when a few do everyone thinks that all of that type of fish get HUGE. Okay I have to admit there are some fish that are way over avrage. It does not happen often thoug. see for yourself, see how many 24 inch doviis you can find on youtube. Just thought I would share this.
