This is my fourth fish tank. I've been wanting neocaridina shrimp (yellow specifically) since I started, but my fish have not been compatible for shrimp breeding (as in they'll eat the fry), and they're not cheap. I understand barbs will eat fry, but are they too zippy for adult shrimp?
Could I have shrimp and Kuhli loaches since they both occupy the bottom? Are gold barbs too busy for the loaches?
What bacteria starter sort of thing would you recommend for biofilm and such for the shrimp to eat? What would you change in my tank to better supply my dream? Can I feed shrimp only veggies? Thanks in advance! 🦐
