The other day I was cleaning 2 of my marimos. After squeezing the water out of them I let them float on the surface and sink down on their own..
In an hour, 1 sank to a spot behind my filter and a plant, which is near a corner. The other marimo was still floating so I went to sleep, when I woke up the marimo has sank next to the other one.

Amazing how these 2 marimo of mine always pair together after I clean them and drop them back in the aquarium, must be some kind of relationship between them lol.

hmm i have 5 marimos in my aquarium. but recently found out 1 of it getting grey color part, been try with fridge spa for 3 weeks. the grey area like expanding still... duno wat should do now. 

PS: the other 4 living very well with Green green color

Add some salt and give them fridge spa should be okay 

I will try if conditions get worst >< don't want to separate them

haha is time for them to enjoy fridge spa 

My marimos go for fridge spa every night b4 i went to sleep  until now still very green haha 

wa, every night? how you do it, just put them in a cup of water with salt and put in the fridge?

haha if u see my previous post u will know where i put my Marimos 

I didn't put salt at all just tap water that's all    and change water every week , give them massage , bath them , roll them 

Haha, I use the tap water to soak and rinse then squeeze them but never in the fridge

Can marimos mix with turtles?

Your turtle will enjoy the marimo buffet

Unless you feed them well I have 15~ longkang guppies and snails in my tank, marimos seem fine with the neighbours..

With fish is ok, but with turtle, turtle basically will eat whenever it able to bite something and their eating period very continuous Guppies is fine with marimos, but snails, bro, it is a bit dangerous as snail main food is algae and they do breed superb fast, last time I tried out, end up one of my marimo become their sarang! LoL
