hey there crayfish peeps!

i just started out this as a hobby and also to make my tank pretty
to all sifus out there, i salute you 

this is my tank of 30cm (L) x 22cm (H) x 20cm (W)
consisting of some plants and my family of marimos
used ADA amazonian soil and 4w submersible filter



then my older sister decided to colour my tank with an orange reddish 2inch dwarf crayfish, which i named Ebi



a very shy Ebi



a close up picture of him/her ( i have not been successful in sexing my little Ebi, yet)



just a week ago, i thought it was suffocating at the bottom of the tank, wriggling around...
turns out, to my relief, it was molting 
then it buffet on its own shell and retreat back to its driftwood home



now Ebi is doing fine and i am deciding to get it a new partner to make some mini Ebis 
thing is, i do not know how to sex it and it is very difficult for me to catch it
so maybe i just get a female to be on the safe side
or any word of advice?

furthermore, Ebi has this huge appetite and it has started eating my water plants even though i have fed it twice a day 
lucky me, Ebi does not munch on my marimo family...
