German Blue Ram Tank Setup
Give them at least 70 litres (18 US gallons). Cichlids are territorial and produce plenty of waste, so strong filtration and some rocks or wood to break up sight lines both help. Aim for 79-86°F and a pH around 5.5-7.
What Do German Blue Rams Eat?
They have small mouths, so stick to small foods: crushed flake, fine granules, and now and then a treat of frozen or live foods such as daphnia or baby brine shrimp. Anything too large simply gets ignored.
German Blue Ram Tank Mates
Males territorial with other males and cichlids during breeding; provide caves and sand substrate. Keep 1 male to 2-3 females. Avoid with aggressive or boisterous tankmates. One of the most popular and hardy Apistogramma species - tank-bred specimens tolerate wider parameters. The German Blue Ram is peaceful, which is the first thing to weigh up when you choose tank mates. Good matches come down to the whole stocking list working together - temperature, tank size, and temperament - not any single label. Before you buy, run your full stocking list through our stocking calculator. It weighs temperament, adult size, and water needs together, which a single species page can't do on its own.
Are German Blue Rams Good for Beginners?
Doable once you test water regularly and catch problems before fish look sick. If this is your first tank, pick something more forgiving and come back later.
