i wouldnt unless your gonna get a bigger tank, Caribe get a lot bigger than Reds,TheDude420;975938; said:One they are stunted from overcrowding the damage is done and they will never reach their full genetic potential. For red belly natts i would recommend 30 gallons per fish.
For example i have 3 reds i a 90 gallon and they should be fine for life. I am actually thinking about adding a caribe or ternetzi.
