Chara (Stonewort)
Chara sp.
Not a true alga but a charophyte — an evolutionary stepping stone between algae and land plants. Whorled branches on brittle stems; produces a distinctive musky smell when crushed. Tolerates very hard, alkaline water that many plants cannot. Often kept deliberately in biotope setups for its unique look.

Codium (Sea Sponge Weed)
Codium sp.
Spongy, dark green dichotomously branched macroalgae with a velvety, foam-like texture. Attaches to rock and can grow quite large. In temperate reef tanks it is a natural part of the fauna; in tropical tanks it can become invasive. Slugs (nudibranchs) and sea hares may graze it.
Compressiceps Cichlid
Altolamprologus compressiceps
Copper Axolotl
Ambystoma mexicanum
Coral Moss
Riccardia chamedryfolia

Coralline Algae
Corallinales spp.
Calcified encrusting algae that paints live rock, glass, and equipment in shades of pink, purple, and white — the hallmark of a mature, healthy reef. Requires stable calcium (400–450 ppm) and alkalinity (8–9 dKH). Does not need dedicated lighting but benefits from reef-level light. Spreads naturally from live rock and purchased plugs.
