There is no need to attack people giving out advice, warf.
The fish you have should reach around a foot when fully grown and they should be supplied with more swimming room and better water quality then you can deliver for that large of fish in a 20 gallon tank.
However, 7 years is actually rather close to how long bullheads generally live for, but I think thats more a testament to their extreme toughness, heck these are the fish that stay alive for days while hooked through the back on a set-line.
Now back to the bad. If you can't properly house the fish, I wouldn't recommend keeping the fish, even if it does live out a full life, it can't possibly be happy stuck in a tank just as wide as it should be long and around twice as long as it.
People on MFK can't force you to do anything, but if you keep up with keeping fish this way you are going to get told a lot that you are incredibly overstocked and the fish you keep are going to be unhappy. And thats no reason for you to attack people trying to help. If you choose to come onto this forum and participate, then you also choose to receive opinions from other members.
It wasn't an attack but an honest suggestion. Just because your bullhead didnt look unhappy doesnt mean he was healthy. Living in such a small environment is what killed him. He was stunted due to high Nitrates and more than likely ammonia and nitrites too (assuming your filtrtion couldnt handle the bio load). You need a bigger tank (for a bigger fish, not the small ones you have now) to help dillute the nitrates so you water stays cleaner longer otherwise they'll build up a lot faster. Also "mommy and daddy" havent bought anything for me, my whole life ive worked for everything i own just as i assume you do. All i was stating was that if you're gonna keep a bigger fish at least properly house it. And welcome to MFK, if you keep an open mind you will learn a lot of valuable information here.
You come to a forum and get a little advice then freak out and show how ignorant and immature you are. Second, sending me the message "Collective minds have decided you're an idiot, please crawl into a whole with filthy disease ridden badgers and die." I think you meant to say "hole" but thanks for the advice
