Shrimple minded Posted February 20, 2015 Report Share Posted February 20, 2015 I'm planning on using a 40 gallon breeder (36" x 18" x 16") to start a new colony........I'm wondering if anyone has any pros or cons they might offer up relating to using a tank of this size. I've read in a couple articles that 10-20 gallon tanks are favored when starting because shrimp can tend to feel uncomfortable and hide if there is too much room and not enough inhabitants. I'm thinking about bringing in approximately 20 shrimp for starters.........would love to hear opinions if the size of a 40 breeder would be an issue. I would guess that some of the potential downsides to using a larger tank revolve around cost..........more substrate, more water, more remineralization, etc. What else should I be factoring in to this equation?

High5's Posted February 20, 2015 Report Share Posted February 20, 2015 Setting up a 40b is costly even if you got it for 1$ per gallon. Lighting, filtration hardscape driftwood/stones and plants/mosses. Quote Link to comment Share on other sites More sharing options...
Greenteam Posted February 20, 2015 Report Share Posted February 20, 2015 One big perk to larger tanks is parameter stability. Quote Link to comment Share on other sites More sharing options...
OblongShrimp Posted February 20, 2015 Report Share Posted February 20, 2015 I use 10, 15, and 40 breeders currently for my shrimp. I have my CRS in a 40 breeder and they do great. It is probably my favorite size tank and can support a very large number of shrimp. I haven't noticed that the shrimp act any different in the larger thanks vs the small.

TheGardenofEder Posted February 20, 2015 Report Share Posted February 20, 2015 I think your worried that with 20 shrimp in a 40 will never see each other. Well I currently have 10 shrimp in a 20 prity much same thing they will do fine if your really worried just get more then 20 shrimp no problem Quote Link to comment Share on other sites More sharing options...
35ppt Posted February 21, 2015 Report Share Posted February 21, 2015 Well I think the other reason people use the 10-20 gal. is so that they can keep shrimps separate, for culling/breeding purposes. So when you have limited space, use 2 x 20gal instead of a 40gal, for example. Quote Link to comment Share on other sites More sharing options...
