Here's what I have going on, I want to grow-out 13 juvies sizes range from 3.5 to 4.5 maybe bigger. I was thinking could I finish growing them out in a 90 gallon tank, I have 7 in a 75 and 6 in a 65 gallon tank. I've been changing water between 2 and 3 times a week, thanks for looking Jim in Ohio.
Also a huge factor is any extra stuff you have in there. Four inches of substrate, rocks, driftwood, big plants etc will displace a ton of water and drastically reduce the # of fish you should keep compared to a BB with only a small piece of driftwood with attached anubias as deco.
Here was my initial post that got deleted
for some reason...."based on what i've read on here, you could keep 13 sub-adults in a 90 for a while. Maybe 10 six inchers indefinitely with SD best practices. How much water do you change out per WC? 80% WC 3x per week would make these guys much more comfortable and healthy than 10% 3x per week."
Do they have to remain as one group? If not why not put 1 in the 65 1 in the 90 and 11 would do nicely in the 90. I was thinking of the 1 fish for 10 gallons that some subscribe to. I a contrarian with 1 fish per 5 gallons. The more fish per gallon the more water changing necessary. You have read that some change water at up 50% per day. If anything I would increase the water changing on the 90 gallon. You did not mention what percent change your are doing 2 or 3 times per week. I am changing daily in an amount that equals 100% per week.
Well I held back one important issue, in the 90 now I have 8 adult discus ranging in size from 6.5 to 5.5"! When I change water I put the fish on there sides and replace with aged water, and all my tanks are BB. So if I put one of my pairs in a breeder tank and the other 6 in 65 gallon can I put 7 juvies in the 90 and the other 6 in the 75 with increased w/c's.
The answer is, of course, you can put the fish in a 90-gallon tank and have them grow up. I don't think you'll get the same size discus unless you up the water change date, but the fish are not going to die if they're cramped. It really comes down to how you're set up to do water changes. Is it a big deal to do one? If not, you can increase the water changes to 5 - 6 times weekly and raise good discus.
