hi guys , i just joined , how r we all

right i have had my rcs for about 7 or 8 months now , started with 13 , they all died unfortunately due to rapid temp change but before the last one died it gave birth , fast forward to now and i have about 200

they are in a 30gallon planted tank , have moved a large amount over to a planted nano tank.So down to my question , i want to put neon tetras or similar fish in the 30g tank with them , but am worried they might eat them all lol , i seem to have a new brood every week or so , so have a wide mix of sizes in there.
any help or tips or suggestions on other fish to have with them.
thanks all in advance
