Yabby tank mates
Cherax destructor
6 rated pairings from the Yabby care guide. Compatibility here means water, temperament, tank zone and adult size all line up — the note on each card says why. Yabby needs at least 20 gallons on its own; every companion adds to that.
Use caution
6 · Works in the right setup; read the note before combining.L333 King Tiger Pleco
Hypancistrus sp. L333
40 gal min · 5" adult · Semi-aggressive
Large, armored pleco may coexist if tank is spacious (40+ gallons) with ample hiding; nocturnal habits reduce conflict but predation risk remains
Anubias Snow White
Anubias barteri var. nana
Hardy plant but Yabbies will uproot and consume it; anchor firmly to hardscape

Pellia Moss
Monosolenium tenerum
Delicate moss easily uprooted and consumed; use as temporary food source rather than permanent décor
Red Hump Eartheater
Geophagus steindachneri
55 gal min · 7" adult · Peaceful
Large cichlid may hold its own but will compete aggressively for territory; requires 55+ gallon tank minimum
Tiger Oscar
Astronotus ocellatus
75 gal min · 14" adult · Semi-aggressive
Large, fast predator may coexist in 75+ gallon setup but will hunt smaller crayfish and invertebrates
Lemon Oscar
Astronotus ocellatus
75 gal min · 14" adult · Semi-aggressive
Similar to Tiger Oscar; size and speed offer survival advantage but aggression levels may escalate
