Shrimp... to count or not to count?

A betta may eat your shrimp, some do some don't.

Also Bumblebee gobies are brackish.

they shrimp will climb all over the plants so they will use some of the vertical space.


They seem to feel more comfortable in groups. I have close to 30 in my 5 gallon tank and they are always out. What type of shrimp are you looking at getting?
I have red cherry shrimp and dwarf green shrimp in my 5 gallon. They breed pretty easily and like hard water.

Wow 10! Are they comforatable in groups that large? Maybe I could go with five then? I don't see getting more than that for my size tank.

What kind of shrimp are we talking about? In my 5 gallon hex, along with some snails, I started with about 15 red cherry shrimp. There have been babies, so I'm sure there are more by now, no idea how many.

If you buy adults, I would go with about 10, and you'll end up with some babies, provided they have some hiding spots and they don't get eaten.

I really think that with less than 10 you wouldn't see them much in an 8 gallon.
 
Ten would be my suggestion as a minimum number to start with too. Recommendations for fish stocking levels do no apply to tiny shrimp like cherries or similar species. They add almost nothing to the bioload. It's not like waiting to see if you have an ammonia spike with adding 10 new fish. They won't have an impact on the tamk parameters.

When you have a tank strictly for breeding the shrimp, they stop growing in population at about 25 for a 10 gallon tank. I'd say each 2-3 need about a gallon to themselves when in a tank (larger than a 2 gallon). You can probably get away with more. I am guessing, 2-3 shrimp would take up almost a gallon of fish space as well.

WHAT? Seems as though my RCS never got that memo.
I have over 50 in a 10 gallon tank and they are still breeding.
I think I see new babies every day. There are always 2-4 that are
berried.

I just had never heard that before!

After seeing the tank, I would say start with five and see how they do, and just add more over time if you want. Five will be okay in it for sure, but there isn't much surface area at the top for water and oxygen to exchange and I am going to guess little filtration/aeration because of the betta. I always point out the biggest ones at the store when I have larger fish to avoid the shrimp becoming lunch for my other fish.

BTW, nice setup!

Agree - those Hex tanks look pretty cool, But the surface area is maybe half of what it would be for the same number of gallons in a traditional tank. I've never had much luck with Hex tanks, I probably over stocked them.

They do not stop at 25! This is a pic from a 10 gallon tank. (The water is changed daily and tested daily and always reads perfect)

P.S. I wouldnt worry about the ratio too strictly as long as your water quality is good and you are not over crowded. :D

Ok so I'm understanding that it isn't so much the bioload I need to worry about with the shrimp as it is the O2 content in the water due to the small surface area of my tank???

Should I get an O2 test kit maybe?
