If anyone remembers i've been trying to find tank mates for my betta, Jim. Well while looking for a new light for my tank at the lfs, i saw these really beautiful reticulated corys. I got a couple of them to try with Jim (corys are on of the few small fish i haven't tried yet).

At first all went well, Jim just completely ignored them and they just started exploring there new enviroment and all was well in Jim land. Today though, when i went to feed the corys, Jim decided to react to them finally. He would try and eat there food, and snip at them if they came near it. I put in a second shrimp pellet and they ate that and he kinda stopped. He still will occasionally flare at them, but he now just sits around them at the bottom and stares at them.

Im hoping its just him getting used to having someone in his tank other then the lone surviving shrimp. I hope.

If push comes to shove they can go into the 20g tank, but that would be pushing it in that tank in terms of amount of fish.

With betta's you just never ever know for sure until you try it unfortunately... I had a betta that really would not tolerate anything else in the tank...he ripped the tail off a corydoras so the poor little guy couldn't swim up to get air and died...I moved the others quick he then demolished all the shrimp in the tank.

My current betta is a sweety and doesn't even blink at anything else in the tank..... he happily swims around with around 30 cherry shrimp and little cory cats.

Great that you have a back up tank ...I think if he is already flaring at them now all the time he may not stop...

i used to have a betta and i put african dwarf frogs in with them. for about the first week he made sure that the frogs knew it was his tank not theirs. i also decided to put fancy guppies with him too, they were more aware that it's was the betta's tank not theirs. i fed the betta first, giving just a little bit of his meal and then i would feed the other fish/frogs too, if he messed with them i would put food right in front of my betta's face. eventually (after a week) he decided his territory was marked and left the frogs and guppies alone. he sometime flared at them but not during meal time.

Its starting to worry me a bit cause hes not letting up. I don't want to have to take them back, but i think my big tank might just be getting close to full if not already there (3 kuhli loaches, 1 dwarf gourami, 1 bristlenose pleco).

Hmm...

I have been through this several times. It took me a long while of bad set ups to realize that only if the betta did not live in the environment first was there not a problem. Most of my bettas will tolerate tank mates but only if they were added last. If you had a small tank to leave him for a while (long enough that he feels like his tank is no longer his but new) you will get better results. This almost never fails for me. Also rearranging the tank before you reintroduce him will be even better.

See i don't have another tank i can shove him in even for a day. Its pretty cold out and i only have the two heaters.

Im thinking either the corys or going back or in the other tank. No matter what ill probably move them into the big tank tomorrow till i figure out what to do.

Maybe you can try again when you get somewhere to put Jim for a while.

I have a Crown Tails which never has bothered any of my Pygmy Corys or Panda Corys.

While my other Fighter male will kill anything near him.

Unfortunately it all depends on the fish to what they will do. It always helps when keeping Bettas and you want to add other fish with them to have a spare cycled tank to place them in just in case the Betta dose not like the fish in his home.

Hope all works out for you.

I had this exact same problem! My betta flared at my cories and would not leave them alone after he figured out they had food. I would even feed them at the same time and he would still go after them. After he nipped the fin of pip, he was put into his own tank. Come to find out later, my roommate had this same problem, only her cories were chased to the point where they got sick and died. It made me sad that they didn't get along at feeding time because when the cories were shuffling around after dinner time he would just hang out with them and mimic their behavior, it was pretty cute.

I use to have a very aggressive Betta.

He use to chase the Rainbow fish around the tank. And he would tire them out. Once he came up to one he would rip it apart very fast.

He was one nice Betta but just very aggressive. He died not long ago. He was one very nice looking Betta though.

See my Betta is mimicing them now, and pretty much leaving them alone. Im not feeding them today in hopes to start tomorrow in trying to train Jim to leave them alone.

Im going to do what dancethenparty suggested and see if i can teach jim to leave them alone at feeding time, which is right now the only problem. Its funny cause he stays at the bottom alot mroe now, and hangs around with them. He used to rarely dive all the way down, and especially rarely ever messed with his caves.

I hope it works out in the end, the Corys i got are so amazing, never even heard of reticulated corys before, and damn are they awesome :D
