Can beginners keep this fish?

This species is generally considered suited to intermediate keepers, since it benefits from some experience with water quality management and feeding routines. It's best to have the basics of filtration and water changes down before taking one on.

Can it be kept with other fish?

They are fairly calm and mix well with many tropical fish. That said, they can squabble with same-species or similarly shaped plecos over hiding spots.

Will it hide during the day?

Yes, they lean strongly nocturnal and often stay hidden under rocks or driftwood during daylight hours. If you want to see them actively moving, watch the tank after the lights go off.

Does it help control algae in the tank?

Yes, their natural grazing on algae makes them a helpful addition for algae control. However, algae alone will not meet their nutritional needs, so regular feeding with pleco tablets or similar foods is still necessary.

What does the "L200" code mean?

It's a common catalog number used to identify pleco species, and the Green Phantom Pleco is sold under this label. Since the same "L200" code is sometimes used for a different species, it's worth confirming the fish's appearance before purchase.

Green Phantom Pleco

The Green Phantom Pleco (L200) is a medium-sized armored catfish with a yellow-green body dotted with fine yellow speckles. In its native range in the upper Orinoco River, it lives among granite crevices, feeding on insects, algae, and mossy growth. Adults grow to roughly 15 to 17 cm, and in the aquarium they tend to keep the same habit of tucking into rocky hides and driftwood gaps. Because they can be sensitive to changing water conditions, they're generally considered better suited to intermediate keepers. Worth noting: the "L200" code is sometimes shared with a different species, so it's worth checking color and spot pattern closely before bringing one home.

About Green Phantom Pleco

The Green Phantom Pleco (L200) is a yellow-green armored catfish native to the upper Orinoco River, reaching about 15-17 cm and best suited to intermediate aquarium keepers.

7 things to know before welcoming a Green Phantom Pleco

1Provide Rock Hides
In the wild these plecos live among granite crevices, so give the tank several hiding spots such as ceramic caves, driftwood, and stacked rockwork. Without enough cover, their shy nature can leave them stressed.
2Mostly Nocturnal
They tend to stay tucked under rocks or driftwood during the day and become active mostly after the lights go off. Feeding in the evening or under dim lighting helps reduce uneaten food.
3Supplement Beyond Algae
They naturally graze on algae, biofilm, and tiny organisms, but a home aquarium rarely provides enough on its own. Supplement with sinking pleco tablets, blanched vegetables, or insect-based foods to round out their diet.
4Plan for Adult Size
Adults reach roughly 15 to 17 cm, so it helps to set up a tank sized for their full-grown length even while they are still young. Floor space and the number of hiding spots matter more here than open swimming room.
5Sensitive to Sudden Changes
Because they come from flowing water in granite riverbeds, sudden shifts in water quality or temperature can stress them. Regular partial water changes and stable filtration go a long way toward keeping them healthy.
6Territorial With Its Own Kind
They are generally peaceful toward other species, but individuals of the same or similarly shaped plecos may squabble over favorite hiding spots. If keeping more than one, provide more hides than fish to ease tension.
7"L200" Can Mean Two Fish
The Green Phantom Pleco is sold under the code "L200," but that same number is sometimes applied to a different species. Check body color and spot pattern carefully before you buy to make sure you are getting the fish you expect.
