Neocaridina have different PH Better in slightly alkaline between 7-8 degree Caridina shrimps doing well in PH 5.8 - 6.8 degree and soft water around 50-120 ppm TDS. So mixing them should be done wisely.
How are the kh on both tanks? Maybe try 60% water changes once or twice a week for 2 months. I took out my Seiri rock because it just kept raising my kh.
Also the shrimp I ordered were Neocardinia. I always mix up Neocardinia and Cardinia.

honey gourami would be alright it'll eat the shrimplets but not the adults so if you let them breed up a bit and add it later u should be alright
