90 l cleaning crew set up.....

[Goose157]

Got my first planted tank set up, 90ltr - co2art se with 2kg fe....everything is running very well. Fish are happy so far....slowly upping the co2....drop checker is telling things are good....
My question is how do I keep it this way....!
I want to get some sort of cleaning crew in there but I have one concern as this is my only tank I have a 3 year old large angle fish in there!......
What can I put in that won’t get eaten??
I really would like some shrimp but I don’t think that would be a good idea.....
Thanks Chris.

Presumably your taking about Angelfish (Pterophyllum scalare) and in short no, your right not a good idea. Most Crustacea are seen as something to be eaten unless their built like a Sherman tank. My suggestion would be
Zebra Nerite Snails (Vittina coromandeliana) and in a 90 Lt aquarium two or three would work well. Don't worry about them breeding as although they can lay eggs in freshwater, the larval stage need brackish to saltwater to grow.
