I’ve been slowly adding fish to my community tank. I have 3 albino Congo tetras, 2 long tail Congos, 3 emerald green Cory’s, one very tiny albino Bristlenose. Now I want to add rainbows. My tank is planted. I’d like to mix Boesemani and turquoise but not sure how many would be realistic. I’m also considering one more Bristlenose. Any suggestions?
