Family Polyclinidae

Aplidium tabascum

Kott, 1992

Sea Squirt

Likely Reef Tank Suitable

Likely Fish-Only Tank Suitable

Range: Indo-West Pacific Ocean

Natural Environment: Inhabits hard substrates, usually under overhangs that are subjected to good water movement.

Aquarium Suitability: Not purposely collected for the home aquarium trade.

Yet may, yet extremely rarely, inadvertently occur on coral specimens/live rock from areas of their collection.

Requires special attention to feeding requirements. For those that want to maintain them, they require numerous feedings per day of live and/or preserved commercial phytoplankton/zooplankton products or that of animal and plant powders that produce suspended products in the bulk water and/or bacteria laden waters.

Proper placement is also quite important. Generally, most prefer low light and do better with indirect light and gentle water movement.

Besides being difficult to maintain, they have a very short life span, usually about one year and sometimes far less. Only those willing to provide for their demanding level of care should attempt keeping them in closed systems. Actually, 99.9% should be left in the wild.
