I was going to recommend a Fluval Nano...I've had good luck with an old Fluval Mini (for 10 gallon tanks - about 15 years old and still going strong)
Thank you guys for your concern.
Here is few photos of the shrimp species currently living in that system:
Different tanks or all in the same tank?
You can go to craft store like hobby lobby and buy shells. I boiled them then placed them in my tank. My multis seems to like them. I have 4 in a community
Excellent centerpiece for a larger tank. Any questions, please pm me. $50. pick up only.
