Hello all. So I've had 10 Cardinal Tetra since January. They are in a planted 29 gallon tank and have been happy and healthy. They were living with some albino corydora, but I recently re-homed them because they were exhibiting stress due to a small school (4). After that a friend of a friend offered to give me some Cherry Shrimp because he had TONS of babies, so I added some cholla wood, mineral balls, and indian almond leaves. I drip acclimated the shrimp and everything has been Aok so far, but I read that Shrimp prefer slighter colder water to reproduce. I have been keeping the tank at 77-78 degrees. Would lowering it to 73-74 be okay for the Cardinals? Thanks!
