I have 3 rcs. I plan to keep a golden mystery snail with them because of the color contrast between them against the black sand. What are some nano fish that are appropriate? I have other colors of snails and would like my fish and snail to be close to the same color, just not red. So black, blue, ivory, or gold. I considered a yellow glow danio school but i dont plan to do the glow lights so don't want to pay the glow fish price hike. Ive heard of endlers but im confused on the color patterns. This is a tank I'm setting up after i post this topic, my 2 females are berried and i want my population back since i bought 9 rcs but 6 died mostly because of the filter. This new tank will have a seeded sponge filter, no more decapitation.
