i do unstand that, but the ones i am mainly talking about are those who get 3-4 monsters cram them in a 55 then come on a web site like these and ask if they have room for another fish. experiance people tell them they are over stock, then u get answer like i dont see how 3 oscar are over stock in my 30 gallon or well my friend has 11 green terrors in his 55 and then they dont take the advise and a couple days later you see pics saying on the line these my new oscar i just brought. then a few weeks laters you read well my fish died and i dont know why. lol
heck now days even on alot of phones you can google or post in a form from. If you really want to get in the hobbie then you will take the time to do the research
