Okay, Petsmart (our local pet store) just got in a new plant that looks like balls of moss.

Are the plants worth getting? They look like they can be dropped in the aquarium and forgotten about?

They run around $8 US.

I just found some other posts on them, so that's great! But I'd still like experienced opinions on whether they are still worth getting, or are they more trouble than they're worth?.

You write about this ??

If they're Marimo moss balls then yes they are pretty easy to care for. No special light or nutrition requirements, just drop them in the tank and occasionally flip them over so all sides get light. You can get them cheaper than petsmart though, I got 5 of them for $25 with free shipping on aquabid awhile back.

They are a great addition to any shrimp tank and are a form of algae. Just drop them in and watch them grow. Yer shrimp will love feedin and cleaning them for u.

Remember, that before put marimo in aquarium you must clean her, because marimo is often very dirty.

How would you clean it?

Fill a bowl with tank water and gently squeeze the marimo several times. You'll see the silt and debris come loose.

and when the silt stops coming off, all is well?

Curiosity is there cladophora isn't moss, but it is algae

Morimo is a "snack bar" for your shrimps, so it is definitely worth having IMO.

or at least, my shrimps love them alot!

please dont call my name wrong . marimo .. not morimo

marimo do well in cool water, and low light, we give pearlies when light is enough , just toss us around regularly to get light on the other size
We grow very slow and shrimps dont eat marimo, just the debris and micro oraganism trap in the algae

Don't they also absorb a lot of nitrate too so a must have in most shrimp tanks?

They are algae.
Algae = algae growing on your plants and driftwood.

ive had a prob of them causing hair algae in my tanks even after i remove them. yes the shrimp like them but i got tired of all the extra cleaning

I absolutely love my Marimo balls. The shrimp seem to love them, too- they are constantly snacking atop them. They are good for nitrate uptake, beautiful, easy to care for and also considered good luck in Japan. Though it is technically an algae, it is a specific filamentous green algae- chlorophyta, which is known to grow in 3 forms: epilithic (colonizing on rocks, etc), free-floating filaments, and the ball form we all know. There isn't much worry about it colonizing all over your tank- if one of the other growth forms IS noticed (which I have never seen in all the time I've kept them), it would be easily corrected due to the very slow growth rate.

It also should not cause an outbreak of hair algae, I've never heard of that...perhaps this was due to other conditions, or hitchhiked in on the marimo ball from another tank? Sorry to hear you had that experience, wicca- they can be great additions to shrimp tanks, especially.

I broke apart my Marimo ball..is that okay? I wanted to try and grow it along some rock I had but it kept coming loose. As being a newbie to all this, yes...even with tying things down, I wanted to make sure that it was okay to break it apart. I ended up just making everything a ball again separately so now I have 3 different sized MMB in my tanks.

I have them in my tank. I cuted them in half and they are okay. In our country they are prety cheap 1 piece is about 1euro :P

Yes these are cool and easy to care for.

I had a moss ball you need to rotate it weekly so that the lights every part of it. took out of my tank and placed in a tank with parrot fish and they demolished it.

my baby shrimp hide under my giant marimo ball (I flattened the bottom a little so it's more of a mound)
