Could I have both a Mandarin and a Six Line in the same tank or would they be too competitive for food and one of them starve to death (most likely the Mandarin since the Six Line is more aggressive)? I know Iââ"šÂ¬Ã¢"žÂ¢m a good 7 months away from this because I donââ"šÂ¬Ã¢"žÂ¢t think my tank is established well enough for a Mandarin. Iââ"šÂ¬Ã¢"žÂ¢m just planning for future inhabitants and trying to get my ducks in a row.
