No matter what they did or the way they stock the tanks someone would always slag them off
Some of the cichlid tanks they do have to be stocked that way to stop aggression
What you also need to take into account is they also maintain the tanks they install so they can add and remove fish as they grow
Them guys do that as a job and make good money out of it yet you slag them off about certain things yet you probably take the word of a spotty teenager who just works in your local fish shop at weekends
Sticking 50 yellow labs in a 40 gallon popcorn tank with no cover is not appropriately stocking cichlids. Also, a shark tank they just did had one of the sharks die. It ran into a decoration and died...another one ate 3 look downs in front of customers. I would say that is inappropriate stocking.
