So petco is having the $1 a gallon sale and couldnt resist a new 40g for $40. Its an awesome tank with a great shape for planting. When my friend asked me what kind of fish I was thinking of getting I told him I wanted to just trasfer evreything from my 20g shrimp tank over to it. (I dont like having more than one tank in my room, its just too much.) He looked at me like I was crazy. My question is, is 40g too much for just shrimp and/or will they benifit in a larger tank? Does anyone else have a 40g breeder shrmp tank? Im thinking about getting a divider to house different shrimp but dont like the look of most dividers.

Buy it and plant it, use CO2 to help grow the individual plants and then resell the plants....the money will finance your shrimp collection which you can keep in smaller breeding tanks. :thumbsup:

I have a 4 ft long x 1ft x 1 ft that I planted with just a few vals (dwarf, corkscrew) some Cabomba and a few different mosses on mesh squares and riccia. I added a T5 light and some CO2. That was in August. :D

My tank is now so overrun with vals, cabomba, moss growing out the ying yang, that I have to now set up another tank to move the Taiwans into, because they can't find one another :frown:

Im going to just keep this tank for plants and use my smaller 8 gallon 12 x 12 x 12 for the Taiwans. Ive figured out how to keep the PH below 6 so thats good for them and CRS too.

A breeder I know keeps his tanks bare except for the soil and some fissidens...I asked why and he told me this way the shrimps can find one another and he can see all the berried females and the babies. He has 100+ gorgeous SSS+ crystals.

Now I KNOW why he keeps it so sparse!!!! Going to do the same thing :proud:

Shrimp can almost always find the female in time. When a female shrimp molts, male shrimp anywhere in a standard aquarium (something you can easily keep in your home) will know about it.

If you start with a single male and single female, you'll still get plenty of breeding. No noticeable lower breeding odds at all.

Should things come down to selectively breeding, a $10 modified breeder box works wonders.

I agree....a male will be able to find a female with ease due to her pheromones that she releases. This is why when a female molts the entire tank goes in a frenzy with all the shrimp swimming around.

I also prefer my tanks to look somewhat presentable. I have a decent amount of girls coming over for some wine/dinner so having 3 bare tanks with a few "lobsters" (as they call it) would not be so cool in their eyes. This is why you add some nice green mosses etc and all of the sudden you become a "different type of guy" in a good way. However, I can see why breeders would want to keep their tanks bare but I am not a professional breeder....I am only a hobbyist. Having plants always gives you a hedge in the hobby; one week I am into plants and the next I'm all about shrimp. It never gets boring. :bounce::bounce:

When I first started in the hobby back in 2005 I had a bare tank if that counts.




But, it quickly became semi-bare with 1/4 of tank having no gravel (these were the days when Cherries were going for 5 bucks).

i think a 40b is just fine for shrimp. and will allow you to be creative on planting it. as for a divider i would go with acrylic or glass and silicone it in place. this will give you 2 tanks where shrimp cant cross over and if need be even 2 different water parameters for say neo's and crystals. you would need double the filters because of making it 2 tanks but that is not to hard

There are so many variables involved (in the linked situation) that it would be super-difficult to pin down.

Put five shrimp in 20,000 gallons of water and there may be some slow breeding. But put five shrimp in 50-500 gallons of water and they'll find each other with ease.

In my experience, the only thing (not related to parameters and health) that seems to slow shrimp breeding down is population density. Specifically, when the tank reaches critical mass, they stop breeding until you trim the population way down.

Yup, I cut down on my population all the time or they slow down a bit. I generally aim for about 100 shrimp in my 20 gallon high. In my small aquarium it's not like the shrimp has to trek across the Sahara desert in order to find a mate.

The linked post in comment 2 is a discussion of the exact opposite experience from GeToChKn. Everybody has such different experiences and opinions.
This is why this hobby is great. Everything is still fairly new so there will always be conflicting opinions. :biggrin:

It's not so much that opinions conflict but that different things work. We're learning all the time that what we once thought were parameter requirements are really flexible.

Really does make the hobby great.

Finding new ways to achieve the same results (especially when a new way is easier) is my favorite part of it all.

Thanks, this is a good theory thread. Everyone gets to chime in on this loved hobby. I think in a few years we can all get a book together. The Planted Tank Group: Tips and Tricks.

Thats a good idea as I am also one week all about plants and next week all about the shrimp.

Why would it be too much? More water = more stable parameters.
Yes more water will help keep is stable. Im thinking too much in the sense of is it neccessary. Of coarse anything will be better off in a bigger body of water. But like hedge fund says, people look at him like he has 10 head with 3 fish tanks with no fish. I know how it feels, the first question is always, "Do you eat them? It must take a whole bunch to make a meal."

You should just let your Multiple Tank Syndrome flourish - don't treat it! :)
Your right. My shrimp tank substate is getting to be ayear old.. And with the couple threads going on now about spent sub and adding sub to existing sub makes me want to ditch the 20g and start a new tank just because of the old sub. But your right, I might just let the shrimp be and do a fish planted tank. Havent had a fish tank in a few years. i seen some pics of triple reds and german rams that I fell inlove with. Ive never seen or heard of them but have been out of the fish game for a while.
