Just wondering how i would go adding some Silvers 50-60mm to the tank with my Trout that are between 100-250mm.

plan on harvesting the bigger trout as soon as they seem big enough, but i wouldnt mind getting some silvers going soon.

also thinking if not i could put the silvers in a 200L barrel inline with my FT Until i grow the trout out to the point where i could Swap the Trout into the smaller tank if there was only 3-4 left and put the 20-30 odd Silvers in my Main Tank.

wouldnt mind just getting 20 more trout but its going to get too bloody hot for them :/

very interested in seeing how the shadehouse controls temps...

My guess is, if you put them all in the same tank. Trout fat and happy, silvers nil!

I would go with the 2nd option of separate tanks than add them to the main tank once you have taken out the trout.

My 2 cents worth.

silvers will be eaten

Look on the bright side... you might get bigger trouts faster...

Yeah, put the silvers in the small tank till the trout are gone. Are you getting the silvers from Ben??

I don't think he has them yet, been talkin to dean from growfresh thinking about letting trout go til I can then harvesting what I can and throwin the rest in a mates dam, then stockin with silvers

... Just of note, my SP and rainbows have been co-habitating just fine for the last few months. I have fish of both varieties and of varying sizes (SP - 100-160mm and trout 150-300mm)

No fatalities, no stress - all are growing jus' fine.

I have heard that territorial issues can prevail - in so far as if the SP are in the tank first, then they should be okay. If the trout were the first in, then SP added, then chances are their days are numbered.

My trout are nasty they ate my comets haha

One choked on a comet and died.

Hi all, This is my first post after lurking here for a while trying to learn as much as I can . looking at putting in a 3 bed system on a 3000l tank (for future expansion) and for water quality stability. Anyhow have looked in the forum and so far not found an answer to this question. If one has been posted my apologies in advance - just point me in the right direction. Anyhow back to the question. Looking at putting the system in around August with fishless cycling completed in September ready for fish. I was looking at putting Silver perch (at 50% capacity of the system) in as I will be coming into summer and then in the autumn when the temps drop put in trout. Will this work? I appreciate as this tread has pointed out that the trout would love it if it was the other way around. Would I be able to continue to do this as the SP get bigger or would they be inclined to have a trout snack.
Cheers

the way around it is too have a smaller tank available to put Silver perch in over winter, 500l ish

i am currently adding to my home system so that i can have trout for winter.

when we move i hope to have the silver in a heated indoor system.

Thats the beauty of haveing a 2,3,4 or ,5. tank system
if the trout can fit a silver in its mouth it will eat it

Thanks for the info. I follow the concept that if a trout can fit a Silver in mouth it will eat it, so the Silvers will just have to grow fast enough over summer to not be snack size by the time the trout arrive in say May. Does this seem reasonable? But then as I understand it they stop growing due to the low temps and the trout start to grow, perhaps into something that could fit a silver in its mouth, I have a problem. Hmm seemed like a nice concept. Perhaps I will need to just stay with the Silvers.
I would love to have multiple tanks but that mean multiple pumps and given that continuous power is a luxury not and given where we live. With the need to have backups would having multiple tanks increase the chance of a system failure?

Cheers

no need for multiple pumps if you incorporate 2 tanks into your design (says he with 2 pumps in one tanks ) just put a SLO or balanceing pipe form one tank to the other

Yep plenty of ways to over come that issue.

Thanks Freoboy , now that makes sense he says when the penny dropped! so rather than one 3000l tank I could have two 1500l tanks that are linked, slightly more expensive and a bigger footpring but more flexibility.
Thanks
