Care reports at a glance

Coverage and gaps

A shop-bought Black Rili female arrived carrying eggs and produced nearly transparent, black and red juveniles. The keeper says she had been housed only with Black Rili.

Four purchased Carbon Rili, two of each sex, produced an initial juvenile cohort with blue-jelly-like animals and a later small juvenile resembling Red Rili.

The accompanying aquarium readings and maintenance context are stored with this observation; they describe one planted system, not tested optimal limits.

A self-described Blue Dream/Carbon Rili colony was established and new juveniles appeared every three to four weeks.

Marc reported no own Carbon Rili offspring yet after unspecified problems; a recently berried female had shed many eggs.

Andy reports years-long Neo survival with little reproduction.

Anfield reports collecting young from a canister filter.

The same keeper describes Amanos as robust.

Kammaroon reports growing Neo colonies despite fish predation.

Baily recalls White Pearls reproducing more readily than Red Fires.

Sweety1984 reports faster White Pearl multiplication beside Red Fire in one aquarium.

Kubiak recommends the nominate form and reports using it as live food.

Epok reports recurring shrimp harvest from indoor tanks and a summer pond.
