Cichlids: Types, Care & Tank Planning

Cichlids are a family of roughly 1,800 accepted species, not one care type. Before buying, identify the exact species and source, then compare adult measurement, usable tank dimensions, social system, territory, tested water, diet and an exit plan. No family-wide minimum tank, water range or tank-mate list is safe.

The classic ram: a jewel-like dwarf cichlid for warm, soft water

The ram (Mikrogeophagus ramirezi) is a small South American dwarf cichlid from the Orinoco basin of Venezuela and Colombia. This listing is the classic colour form, often sold as the German blue ram: a golden-yellow front, iridescent blue spangling, a black bar through the red eye and a dark spot on the flank. Males have taller, longer dorsal fins; females are smaller with a pink belly.

This listing sells single, unsexed fish. Other colour forms, such as the black ram, are separate listings.

What you receive

One quantity is one live ram of about 3–4 cm, unsexed. Buy several if you hope to form a pair.

Aquarium and water

A mature, planted aquarium of about 54 litres or more for a pair, with soft sand, roots, flat stones and gentle flow. Rams need warm, soft, slightly acidic water — 27–30°C, pH 5.0–7.0 and 1–10 dGH (Seriously Fish) — and very clean water, so add them only to a fully cycled aquarium and change water regularly.

Feeding

Feed small sinking pellets and micro-granules with frozen bloodworm, brine shrimp and Daphnia, in small portions once or twice a day; rams feed near the bottom and can be outcompeted by fast fish.

Tank mates and behaviour

Peaceful with small, calm fish that like warm, soft water, such as small tetras, pencilfish and Corydoras that tolerate the temperature. Avoid large or boisterous cichlids and fast fish that take all the food.

Follow the arrival sequence before releasing the fish

Tropical Fish Co’s delivery and Live Arrival Guarantee policy explains the packing and arrival procedure. Livestock is hand-bagged in pure oxygen and placed in an insulated poly box, with a heat pack when the weather calls for it. Someone must be at the address to receive the parcel because live animals cannot be left unattended.

  1. Receive the parcel in person and start filming before opening it. Show the parcel still sealed with the outer box visible.
  2. Open the parcel in one continuous take. Keep filming until the fish can be seen inside the sealed bag before anything is disturbed.
  3. Float the bag for 20–30 minutes so the temperature equalises slowly.
  4. Do not pour the bag water into the aquarium. Release the fish without adding transport water to the established system.

If a Live Arrival Guarantee claim is required, contact us on the same day with the order number and the continuous unboxing video. Before the parcel arrives, confirm that ammonia and nitrite read zero and that the aquarium matches the water values on this page.

    I have a small group of long finned mountain minnows. So was delighted to be able to order ten of this variety to increase the genetics in my tank . The ones I recieved are healthy but it’s to early to give a verdict on wether they are of a long finned type since they are small currently.

    100% success travel and "installation". Pleased with quality of purchase. The Siamese fighter a bit "shy" so have not yet seen him at his best yet but looking good. Happy customer. GG
