No they dont. Cherry are neocadinas they cant breed with crystals or any cardina. Neocardins prefer hard water and temperature to be tad warmer then cardina. Cardina prefers soft water and lower temperature. They are also more fragile then neocardinas. High nitrates, ammonia, will kill them. From what I read cardina not for beginners but if you research them it can be done....just note they aren't as cheap as neo. I also read if you keep both groups together you should do the water should be for the cardina preference. Real plants are amazing. Shrimp will graze off of them. The easiest plants to keep alive are java moss and java fern, anubias. Floating plants are also great.. most people don't like duck weed but from what I saw on YouTube shrimp apprentely love it. I have frog bit too (another floater.) Floaters help with nitrates which I have a issue with.i also have driftwood I bought from pet store. It can help soften the water and again another food source. It creates biofilm. Which shrimp loves. I also feed a little bug bites pellets. Just enough that they can eat within a hour.im not an expert at this but I been reading up on them.
