Hello Everyone. This is my first post ever on a community site of any kind.
I am setting up my standard 125. I want to keep a few peacock bass, an arowana, columbian shark, and a tiger shovel nose cat. I have a fluval 405 cannister filter, a couple power heads, and an air pump. Will these fish be good tank mates? I knw they will grow too big for the tank and I have a place I can take them to when that happens.

My biggest concern is circulation and water flow. I have the intake and exhaust on opposite sides of the tank. Should I use any power heads? I want the flow/current like a river but I dont want to stress arowana at the top, and I want to make sure there are no dead spots around the tank.

Please tell me what to do. I am open to all advice/suggestions. How should I position the gear? Should I move the water one way or try and complete the circuit? Should I exhaust the filter at the top and set up a power head mid level? Just tell me what to do.

The tank has been cycling for a week. There is one large pleco in there. I am feeding him algae discs.
 
Man I have a 125 with less stock and am runnin a FX5 and an XP4 and still having to clean at least twice a week with my 2 oscars creating a mess. I think you woudl need a lot more filtration for that tank and those fish woudl be out of there and into a larger home pretty quickly...

haha i have 2 xp4s and a 405 on my 125 and Im thinking about adding another 405...you need more filtration for sure at least one more canister then maintenance is easy you can clean one while the other is running
 
also...get a spraybar for your 405 and position it right at the water line for good flow and circulation

Is this the permanent or a grow out tank?

A standard 125g is only 18" wide, this does not work well for arowana in a long term setting. You will need a wider tank for one of these or you will be re-homing him pretty quickly.

Peacock bass get big so do tiger shovel nose cats. You need much bigger tank as was mentioned.

The columbian Shark or silver tipped needs brackish water as it gets older so also not a good choice to go with the others long term.

I was not trying to burst your bubble but a 125g is not big enough for all those fish together let alone some by themselves.
 
Wow,

Thanks for the info everyone.

I'd love a bigger tank but the 125 is all I can do for a few years until I get a bigger house. It fits perfect where the TV would go in a normal house LOL. What would be a good choice for a bottom feeding catfish? I'll skip the shovel nose cat and just get the arowana and peacocks for now. Do you think I could get at least a year out of these fish in the 125?
 
I still think the 125 woudl be too small for a few bass and arawana like you initially posted. It is not that large for them to turn around as they get older. Sure you could get a year out of it perhaps but then they would have to get into a larger tank.

If you are staying in that house for a few years like you say and you need a tank in tha spot then you are limiting your fish selections and would think you should point yourself in another direction...but thats just me.
 
I dont mind swapping these fish all the time. I can catch the peacock bass from my brother's backyard when the babies are around and there is a local guy that get's small arowana's for $20.

I guess I could get a deeper tank but 72" is all the length I can fit. What size tank is 72" x 24" deep? I'll keep an eye out. I can extend the stand for the larger depth.
