Siamese Algae Eater tank mates
Every recommendation below is computed, not copied: the AquaSage engine paired Siamese Algae Eater (15 cm / 5.9 in, peaceful) with 271 fish and invertebrates in a spacious reference tank and scored each pair for water-parameter overlap, temperament, predation and husbandry. A species makes the green list only when every check passes at 20–26 °C (68–78.8 °F).
Verdicts by the AquaSage engine v0.1.2 in a 450 L reference tank. Read the full methodology →
