i have three zebra danios in my 10g and my smallest one is about half an inch and its always constanly chased forever until the bigger one stops but he seems fine. no ripped fins or anything but its kind of scary thinking it might get onto the swordtail. any help?

Zebra danios really should be kept in schools of 6 or more, so thats probably why their bullying the smallest one.

Zebra Danios are always chasing each other, I wouldn't worry about it.

I agree with Megustaunapez...upping the school will probably help...but theres also a pecking order they establish..maybe get a few more and have some the same size as your small guy will help

Got to agree here, move the danios out of the 10gal to a bigger tank and add at least 3 more and watch the change. Danios need swim room they are really active swimmers so the longer the tank the better. 10gals really isnt big wnough for them even in a full school

mr. Clown Loach

thing is i don't have another tank for them and i don't think i can fit anymore in there because i need bottom feeders and baddly because they mainly eat the food and spit it back out...

Jonah

Dannios are not bottom cleaners, corys, khulis and BN plecos are bottom feeders. danios are mid to top of the tank schooling fish. Best thing to do would be to put them in your 60gal and add 3 more. Then get 3 Kuli loaches to clean the bottom of your 11gal( 4" fish but 2" bio-load) or 3small corys like Albinos or Pandas

mr. Clown Loach

ugh i know danios aren't bottom feeders i was saying i need some and my big 63g is already overstocked and my 10g is about to be full because of my swordtail.

i have 30g tank and i have 6 of them.. those are only 6 i have. one is little bigger than others and constantly chasing others to the point i get scared. lol.. i was planning to put in neon and cardinal school of 6. because of that one aggressive one i am debating. should i remove him? or will it not bother neon and cardinals and only chase zebra danios?
