I have kept TSN and RTC with my micros and they worked just fine,just make sure that either fishes wouldn't be too small to be swallowed by anyone,ur main problem here is its growth rate coz sooner or later either fish will overgrow the other,but as i have observed the tsn,rtc and micros have a pretty close growth rate,well this depends on the fish,coz i have 3 SH of the same size but after a month 1 of them have grown from 2.5 inch to 12 inches in 1 month while smallest just reached 8 inches making the 12 incher swallow my 4 inched archerfish(2pcs)
