My 120 Gallon Aquarium

Video slide show of my 120 gallon tanks inhabitants  Most of these fish have spent close to 5 years together.

Unless this is a grow out tank, I think your stocking is terrible to be honest

Regardless of weather it is 4 or 5ft long, I would definitely remove the dovii unless you enjoy seeing a fish that can barely turn around, not to mention the fact that it will probably kill everything else in the tank.
Then there's the fact that it is terribly overstocked and contains fish that thrive from very different water conditions. Just out of curiosity, what is your full stock list?

The dovii has been in this tank for 2 years now...shes in it for grow out purposes so one day I can introduce her to my male.  Like I said, most of these fish have been together 5 years and are all in perfect health.  The biological filtration on this tank is A1 and the water is pristine...good thing you didn't see the Mono Sebae who is 9 inches in height and has thrived in pure fresh water for 5 years  now.  Overstocked is a term used when a fish can't live up to its full potential based on the aquarium conditions they're kept in (eg : tanks to small, filtration is inadequate or there is too much aggression).  None of my fish are malnourished or are suffering from stress related through aggression or small tank size...if anything, most have exceeded expectation eg: my largest clown loach is now close to 11 inches.  Stocklist will be added to the video hopefully soon

Well that's good then. I bet that male is a sight to see!
I noticed you had pikes as well, do you know what species they are?
Seen as I don't know your stocking, it would be unfair to criticize you but your tank does look fairly cramped. At the end of the day though, I doubt my opinion would change your mind anyway...

Yeah the male dovii is very nice (check him out on Youtube).  The pike is a variety of saxatilis...I have it listed as "Alta" but I think I'm wrong.  I've been keeping fish very long (over 25 years) and have kept almost everything under the sun.  I base everything I do on observation and experience now (wait till you see my new mbuna setup) but I also have lots of aquariums so if something doesn't going well, I have the option to move the fish

Im all for experimentation but CRIKEY!!!
 
I know its not going to change anything with your tank but I do think that a large proportion of the tank is luck.... like those goldfish that live for 20+ years in a bowl. You also have the advantage (by the sounds of it) that you have multiple tanks.
 
All I can say is - other members I beg you not to use this tank as an example, the chances of it being as successfully replicated are so so slim...
 
Other than that I dont have a clue what to say Im pretty shocked...

Nice fish.

Seriously mate, it looks fascinating with all the fish but you just cant.when i started i overstocked my tank but disease broke out and i lost my fish.The fish may look happy and stress free but how do you know. we cant test for it.
 
you said you have other tanks so why dont you separate the fish into the tanks, trust me It will still look good.you may look at my age (15) and think who am i to tell you but a person like you having kept fish for over 25 year should know you cant keep fish in this way.

As Will said, that is hard to replicate by a non-expirienced fish keeper and is to be avoided if you can help it.  But from an overstocked to another overstocked tank there can be miles difference starting from amount of filtration, water change regime, feeding, etc..The only thing one can't avoid is aggression and crowding if the fish can't get on. But many skittish or aggressive fish like some degree of crowding to feel better so it all depends. As for what water conditions each fish requires, that's another point. Many fish adapt to a wide range, some don't.
 
I keep remembering something I read about growing discus fish. The guy that figured they need lots of water changes while they grow made an experiment. He separated fry from the same batch in two different tanks. One was so small that the discus could barely swim around and had no filtration of any kind. The other was bigger and with a cycled filter.  He did 7-8 daily water changes on the smaller tank and one large water change daily on the bigger tank. Both tanks were fed the same food and amount. In two months the fish in the small tank without filtration but lots of water changes were 2 times bigger than their siblings in the bigger, filtered tank that got just one large daily water change.
