Special requirements

  • Equipment Protection

    Known to physically break internal equipment. Submersible heaters should be fitted with guards or, ideally, situated externally in a sump or inline.

  • Massive Waste Management

    Exceedingly messy feeders. Requires oversized filtration and a strict 30-50% weekly water change schedule to prevent Nitrate buildup.

  • Interactive/Destructive Decor

    Will actively dig and 'redecorate' the aquarium. Rooted plants will be destroyed. Use heavy driftwood or rocks that cannot be easily shifted.

  • Hunting Behavior (Thanatosis)

    Some wild populations use 'death-feigning' strategies to lure prey. In captivity, they are highly intelligent and will 'beg' for food from their owners.
