German Blue Ram tank mates

German blue ram tank mates only make sense in warm, soft, clean water. Dither tetras and cories can share a calm community; cool tanks, nitrate creep, and nippy barbs erase rams before compatibility charts matter. Farm-bred weakness means quarantine and stable chemistry beat any mate list you copy from a forum.

Common mistakeRunning the tank at twenty-four degrees to match cool community fish is how keepers invent ich and internal parasites in rams. They need roughly twenty-seven to thirty degrees. Below twenty-six, immune function drops — warm the dwarf cichlid plan, or skip the species instead of compromising for tetras.
