I know i'm asking for trouble but....
Been having terrible luck creating a large school of cardinals. Bought 15 from lfs, most died, a week later bought 10 from different lfs (they were not eating at the time) and most died. Had five still alive after this.
Bought 30 from Drs. Foster & Smith last week. Shipped overnight from LA to Richmond. Since last thursday have lost 25. Big ich outbreak. Did 2 hour acclimation with lights out, 1/2 cup water added every 5 min for 1 hour, emptied 1/2 water and did it again, finally gently netting out the fish. Been treating ich since Sat.
Tank params are generally ok. Tank is 3 mths old. Still have 10 alive (probably the old 5 plus 5 from this last iched batch). Have not lost any corys, otos, or loaches (have had them all over 2 months).
I swear I don't think I am causing these deaths. I watch everything closely
pH = 6.6
KH = 4-5
PO4 = 2-4
CO2 = 35-40 (off at night with the lights)
NO3 = 10-15
Temp = 78 degrees
Plants pearl at night so O2 is not a problem
So heres the crazy question:
I want to add 4 3-4" discus. (have wanted a planted discus tank for 4 years, just afraid to do it!) I have given up on a school of 35 cardinals. Is it ludicrous to consider the discus. 2 or 3 wc per week is no problem for me.
If I have had so much trouble with cardinals, does it portend bad things happening if I add discus?
