My 29 gal. tank is ready to go, and I decided to rescue a betta from his little cup today!! Will my plan of harlequin rasboras and pristella tetras still work, along with the betta? From what I've read, neither in general are real aggressive or fin nippers..what does anyone think? ??? Thanks!!
Thank you all.....I also asked at the LFS today and was told that the harlequin rasboras would probably be ok but the tetras were iffy.....I may try cherry barbs instead.....the chart you sent me is a handy tool, too, Rose and I thank you!! Yes,the betta seems to be enjoying the 29 gal!! ;D I"ll try to get some more pictures posted soon!
Here, try this one. Though you must be careful. For instance, yes my Betta is compatible with my Corys but it took about a day before he accepted them; before that he was chasing them every time they swam through the tank, especially when they swam up and down the sides near the duckweed. I had to remove some of it and give him a smaller area to call his own, then he sort of calmed down a bit. Now they all swim close together and it's fine.
One thing to remember is that a male betta has been a solitary fish in a container by himself since he was old enough to be a problem to other male bettas. He does not know how to "play nice" with other fish right away and is prone to be quite curious about things. He gets very territorial if he is the first fish in the tank and the others are added later. The best way is to add the betta LAST. Then everyone else has a territory and he has to fit in instead of everyone else finding room in HIS house. (which he does NOT like to share) They will chase and harass all the other fish that are new for a time. But if they follow the rule like mine they don't hurt the other fish, just scare them a little. (and show them who is BOSS) I have seen a lessening in this behavior with Noel, but unfortunately not with Marty. I think it might have something to do with his youth. He isn't 6 months old yet. I figure I am still having to put up with his puberty. :
Initially my betta would chase the red platys, not so much the blues- don't know if he was possilby attracted to the brighter color? The otos were added last and he's never bothered them. At this point everyone seems to be getting along fine!!
I think Harlequin would be fine but a lot of tetras are nippy. I don't know anything about Pristellas. I think Lemon Tetras and Cardinal Tetras are more peaceful/less nippy than other ones, but do some research before deciding what to get. Lemons are a lot more hardy than Cardinals, if that influences your decision, but I'm not positive about them being not nippy... Barbs are definitely a no-no with Bettas.
I understand that cherry barbs CAN be kept with them. I'm not sure about some of the other species in the compatibility charts. You might want to make sure you can return incompatible fish or that you have an alternate suitable tank for them.
Although I wouldn't recommend putting them in with a betta in anything less than 10 gallons.
I had a betta and 2 ADF's and when I added a dwarf gouramI (seperated by a tank divider, temporarily), the frogs got upset by the limited amt of space and started going after my betta's fins. The tank divider limited the betta's and frogs space probably from 10 gallons to 6 or so.
