I understand that, you do realize you are asking someone to change out 27.5 to 55 gallons of water a day in their tank? I'm not trying to be hard on you but you are advising that they do a lot of unnecessary work.
They said their ammonia is testing at .25 ppm
, that's not even toxic to the fish, and with only 2 small fish in the tank it's not likely to raise up very quickly at all. If the OP feeds lightly it may not need to be changed but once a week.
The best route would be to continue testing regularly and do a PWC
as needed. If it were me, at lets say 78 degrees and 7.5 ph, I would probably wait till it tested at 1 ppm
before doing a water change.
A couple of concerns are the stocking, for one, if they are all red tailed sharks or in that same family then they have a great potential to hurt/kill one another because they are known to be very territorial towards their own kind.
Also, they do not make very good candidates for fish-in cycling and do best in a more stable and established tank. One sign that they are stressed is if you see the red in the tails pale out, it'll tell you a lot.
