What all can you put in Small tanks?

I recently acquired two small tanks (a 1 gallon and a 1.7 gallon) and was wondering if there was anything besides maybe plants that I could put in them? Otherwise we might just use them as isolation tanks for like dosing medication or tiny fry (from like galaxy rasbora).

 

I'd definitely make them into shrimp tanks.

 

cherry shrimp tanks all the way!

 

Ok! That works out well. Wish I could upgrade the light on them, but the one is part of the hood and filter .... the other, the hex, I have no idea where I would get a better light that would fit it ... besides the LED clip on ones. Any ideas?

 

OK, OP's husband here. I was going thorugh Aqadvisor for figuring out how many of what I can put into the 1.7g tank, and I'm kinda confused...

If I had a SINGLE cherry red shrimp, it says I am 5000% overstocked. is that a bug on the site?

 

AqAdvisor isn't the best with inverts, you could probably get away with over ten.

 

I would say that 1 RCS in a 1.7 gallon is definitely not 5000% stocked. I would start with 5 or so and see how many you end up with. They are very prolific.

 

Yeah, I was kinda hoping for a tank I could start a good colony for seeding our other tanks that have fish in them.

 

At least till we can afford to get a larger tank for his desk like my 5.5g
