Hey All,

So my girlfriend and I were at the LFS and she really likes the cardinal tetras. The only problem is I don't know if they will eat my RCS that I currently have in the tank. Does anyone have experience with these to in the same tank or can give me some advice.

Thanks.

I have Cherry Shrimp and Cardinal Tetras in a heavily planted tank. Cardinals can eat babies but don't show interest in anything above a 1/4 of an inch. Cherrys breed so fast that Cardinals won't affect the population too much. I have 12 Cardinals, 10 Hengels Rasboras and 8 or more guppies. I year ago I bought 6 Red Cherries to see if they would survive and within a month I had babies measuring 1/8 inch or less all over the tank. They had no trouble living to adulthood. In a year, the numbers are approximating 100 or so. The baby younger shrimp often swim amongst the fish being confident in their abilities to out swim any threat. I think baby shrimp are more capable of out swimming predators than baby guppies are, yet my guppies also reproduce without problem in my planted tank. Also, I don't really specificly feed the shrimp. With the algae, detritus and fish food, the shrimp can easily over populate my tank.

The idea of keeping any fish with my shrimp makes me shiver! But if your goal is to just have a diverse aquarium the cardinals will not mess with adults but they will eat the young! Young shrimp grow fast and if they have a good amount of hiding places many will survive!

Ok. Other options that we are looking into for fish in the shrimp (RCS) tank is nano-fish like the rasboras but I am sure the same information applies to them as the cardinals.
