Required tank size

  • We are currently upgrading MFK. thanks! -neo
If you really want a good shot at a forever home for all those fish, especially if you have males, I would say more like 300 gallons. 180 would be a good size for a singe male managuense for exmaple, but I doubt it would be able to live peacefully with the others who also will get bulky and are all quite mean usually. 180 might last you a good while, but not forever imo. 300 will give you a good chance, but still no guarantees with these species.
Agree with this above.
I have kept all the fish you mention except the FH (but I have kept true trimacs) and have a 180 at the moment and wouldn't dream of combining all the fish you mention together as adults, in that size tank.

Even in a 8ft 300g, a mellow jag will pin other fish in the other 3-4 feet of a tank. That’s a mellow jag, a more aggressive one will do worse, from shredding fins to killing.

the flower horn and mayan might work but the jags ussally go crazy once they put on some size but check out palmer aquatics on youtube he had a 125g setup with jags red devils and I believe he has even had a couple FH in their too

:screwy:

Looks like 2 fish already have tails split all the way up.
 
Note the aggression but also take into consideration the bio load. My common is a poo factory at only 2 years old.

I mean it can be done but you will be constantly battling aggression maybe try it but make sure you have a spare tank incase one fish is picking on the other
I'll try to avoid this. Don't want to wake up one morning to find one fish seriously injured..or worse
