View Full Version : The Color in this Blue Phantom Pleco

The change in color in this Blue Phantom Pleco is so strange.When I first got this fish, maybe 6 months ago ( appx.) it was a dark blue. It then started to change to a lighter blue and now is a mottled blue/green. Wonder if it is going to stay this way ( it has been at this stage for about 6 weeks now) or turn all green.

Here is picture when first got the Blue Phantom Pleco:


Strange isnt it?

Very strange! Must be trying to blend in with the plants lol

He's very very pretty! He certainly camouflages but stands out at the same time haha.

Oh my, he is so pretty! Does he stay out and about for you? I hope you get to admire him often.

I'm a little late to this party, but Wow, that's a beauty!

Agreed, beautiful fish...male, female?...about how long is it?

Yeah, i'm curious how big this pleco will grow? I can't believe I sold my friend's tank with one of these. I kept her tiger pleco pair, but sold the lone blue phantom. I think he costed her 70$ to buy initially, if I know he would look like that, I would have never sold it!

SThanks :) he actually is out quite a bit. She does swim to the back when she sees me go by the tank, but for the most part is visible most of the time.

Id say she is approximately 7.5-8 inches. Maybe less @ 7. I would have to take her out and measure.

Wow, she's a big 'un, lol...maybe not done growing yet, too

That's about as big as they get, and he is a beauty. Definitely a boy due to the odontodes on head and first pectoral ray.

Funny its states that they may be related to L200 Hemiancistrus subviridis -Green Phantom (not the herbivore hi-fin variety; Baryancistrus demantoides), so maybe he can change color?

B. demantoides (hi-fin vegetarian) right, H. subvirdis (similar to blue phantom) left

Have been wanting a phantom (blue or green) for a very long time. This one is just stunning, I like him better molted. What do you feed him?

Thank you, you think its a male? Someone else told me female, so I just went with that- I sure dont know.
He/she eats everything I feed my discus, its in my discus tank: bloodworms, NLS Pellets ( Algaemax, cichlid), Freeze-dried Blackworms, and I give an Algae wafer daily. This fish is always hungry.
Keeps the tank clear of Algae and also eats bio-film offdriftwood.

Yes I believe that is a male with a healthy appetite, lol.

A couple of nice video's I found of them

Guy seems to know a lot about them

Great videos! Thank you Lee!
Mine is definitely at the 7 inch range- it is a pleco that is very, very willing to eat anything you give it. Not at all fussy.
And very docile- I have it with my discus. When it is actively eating on bottom, however, it is very robust and moves around quickly so slower bottom fish would get edged out for food. Thats why I dont keep any other Pleco's with it. I felt like it would not allow other Pleco's to get any food. Maybe, that is not true. It seems to not be a problem with others who have kept them.
Mine has slowly become more green in the body and kept blue in the fins. It started out as a midnight blue, went to a lighter blue, and then began to blotch with green. Like the picture. Really unusual.

We need vid of yours, actively eating, please and thank you

Maybe a nice big piece of blanched veggie?

I never do give him blanched veggies- bad mommy. I will take a video soon :)

I'm sure your gut feeling about keeping him as the only bottom feeder is exactly right.
You say his coloration is unusual. It certainly is beautiful! I'm so glad for you, that you enjoy him.
