please help me build my first predator tank

  • We are currently upgrading MFK. thanks! -neo
That size tank is fine for most of the upper jaw bichirs. Delhelzi, polli, palmas, sen would all be fine in that tank. mokelembembe as well
 
Never kept gars befor, but the very most channas do best in a species only tank.
Dwarf barracuda tetras are small and slender and will possibly be eaten by bichirs and the others too.
 
ok final
please suggest fish that i can find here
so that means there is no options for me
ok so now tell me what i should do then ?????
i just need 5 predator fish species for 4/2/2 ft tank
for future i will go for bigger tank for other predator fish
 
Hi, why 5 different predators in one tank?
Why not one or two species, but more fish of each?
Why not look for one kind of fish, that you like best, then plan the other ones matching?
And many predators hunt any other fish that's why they are called predators.


As it has been written before, you could keep 5 different, smaller bichirs in there.
I think a 3x2x2 is a little small, but 4x2x2 is sufficient.
You change the tank size constantly: 44 inch, 7 ft, 3 ft or 4 ft long.
Better think what you want, then how to get there!

i have only space for 44/24/18 , which is 312 litre , right now, so

pure predator -
here in market i only can find red tail cat , paroon,bass, gar,bichir,arowana,arapaima, as pure predator fish
other is-
parrot, oscar,flowerhorn, red devil, piranha,paku, green terror, jewel as an mean aggressive fish

those fish are common and readily available here
 
It depends, when they are full grown, other fish should be at least 3-4 inches long and not too slim.
Some had success with kribs, or larger barbs, others even lost angelfish.
Avoid plecos, as they can suck the bichirs slime coat!
The bichirs should be introduced as last fish.
Otherwise, new tankmates would be seen as food.
Most of the fish in the video will grow out the 100 gallon pretty fast.
