Chiclid tank got me thinking.....
Ive heard of people overcrowding chiclid tanks to lower aggression on one particular fish, assuming they have correct filter and good water maintenance. So that brings me to my question.

Could you do that with female bettas in a ten gallon tank?? I have four in a ten gallon and would like to add some more once the ones i have now are healthy. I have a whisper 10i filter. What % of the water would i need to change every week?? Its planted so that would help with ammonia and what not.

Your thoughts??

I would think that four in a 10 gallon is the upper end of your tank/filter capacity. Seeing as bettas are a sedate fish, I don't think they would do well in the water flow that you would generate while trying to overfilter an overloaded tank... particularly a small one.

It's the same thing, just applied to a different kind of fish. I don't know enough about betta "sororities" to comment on its effectiveness. However, I know enough about bettas to say that they are not territorial in the same way as African cichlids, so I would think its likely to not work the same way. With Africans, because of the way that territories are carved up in the tank and because of the number of threats to each's territory, it is sufficient for them to simply drive the other fish out. Because bettas don't have such well defined territories, I think one is more likely to follow another around, an there is MUCH more fin to be nipped. Some people think that their fishs fins have to be perfect, however, when keeping more aggressive fish, this is not always attainable. I know in my experience as a professional fisherman, it's very common to see less than perfect fins. With regular fish, it's not really that big a deal, aesthetically speaking. However, bettas have beautiful fins that don't look good when they are damaged, and they don't heal as well as regular fish. Personally, I keep fish in part to admire their beauty, and since a significant portion of a bettas beuaty is tied up in its fins, I would be very hesitant to subject them to conditions that might result in them having anything but beautiful fins. But that's just me.

JDM - By "upper end of filter capacity" do you count just the filter?? Or plants too?? I want to bump it back up to 5 bettas, like it was before he turned out to be a male >.< Filter capacity has always confused me

Jaysee - Good point on how they would look. I hadn't thought of that before. I think ill just add one betta after my two sick ones are better, so there more focused on each other. Would adding shrimp be a good idea??

Are Shrimp a good idea? In what regard? What species?

Pearl2011 03-28-2013 11:27 PM

Red cherry shrimp. By good idea I mean will they all get eaten?? I have anacharis for them to hide in, but will that be enough??

jaysee 03-28-2013 11:56 PM

Yes, they will get eaten - shrimp are at the bottom of the aquatic food chain. Will they all be eaten? Only one way to find out. I think the best thing to do would be to let the shrimp colony establish itself prior to the bettas being in the tank. Probably not possible though. There's really only one way to find out if it'll work for you...

4 bettas in a 10 gallon is just getting full, 5 would probably be fine. It does make a difference if they are all of the same species as I understand that you can get away with more numbers due the less stress with no interspecies issues... and females are smaller than males I think. If you have planted lots of plants, the filter is really just for circulation and to remove particles from the water for your viewing pleasure so it's the filter that I don't count, as long as it is right sized for the tank.

I added shrimp, cherry shrimp. I started with 4 and figured that if all four were still there a week later I would up the numbers. They were, I went to 10 and I cannot tell if we have 10 anymore but I do see as many as four at a time so I suspect they were OK.

Having said that, they are in a 37 gallon tank with craggy driftwood that hey can hang out in. The fish cannot at them like they might in a plant but I have seen no fish actually try to take a bite out of one as they are fast.

Oh, see if you can get mostly grown ones, 7/8" is a decent size as they don't fit in anyone's mouth very well so they have a better chance.

Unfortunately I only have two bettas now and will be getting a divider tomorrow. Would they have a better chance with the more docile betta?? I don't think I have ever seen her chase another fish expect when I first set it up. A nice big clump of anacharis would help, I guess.

We'll see what i do with this tank. Not sure since I had to euthanize two fish yesterday :(

In my sorority, adding more girls hasn't been a problem. newbies might get a little scarced, or try bossing the others around, but everyone settles down in a week or two. i overstock a bit, and think if jts well planted you'd be fine with six or seven girls in a ten gallon. i also don't subscribe to the "remove everyone, rearrange, readd in order of aggression" theory. hasn't made a difference for me.

my girls, though, would NOT do well with shrimp. they absolutely DESTROY snails. there are so many big ramshorn shells laying empty around that tank, i know they'd destroy shrimp. However i have a very chill male who has five ghost shrimp buddies in his tank that he ignores.
