I have one electric blue ram female who has been doing great for months and I would like to add more. My tank is a 37 gallon tall high tech and heavily planted. How many German Blue rams do you think would work? I've heard a range so I'm asking others. I was thinking 4 to 6, it is not possible for me to get sexed fish so I may have to roll the dice there. I have heard the inch per gallon thing isn't accurate and planted tanks can do more than that. I know for a great aquascape and photograph that a bunch of fish can be distracting, but i'm going for something that is great in my living room and fish are nice with all the plants. Other fauna: cardinal tetras, furcata rainbows, SAE's, otos, shrimp, and nerite snails. I may like to add a few lace gouramis if I could.
