wicca27 i think im going to end up selling my school of columbians. i hate to but dont think they would do well with a 625 mile move and no tellin when i could get the big tank set up. my husband will be gettin out of the army by the end of the year and we are not even sure where we are moving yet.......

driftwoodhunter My Columbians are as peaceful as can be - I have 18 in a 125, but they are housed with Buenos Aries tetras (10) and they all school together. Maybe the quantity makes the difference. my Columbians spawned last summer - I originally had 12 - and the few I couldn't catch stayed in the tank. The survivors are what brought the number in the tank up to 18. However the 45 or so fry that I caught are now an inch long in their own tank. Soon I hope to be moving them to both a 55 and a 90.

There are also a few Black Neons, Harlequin Rasboras, and two pita Blue tetras in the 125 - the Columbians have never approached or harassed any fish.

scokaw Columbians are my favorite tetras, and i would agree that they are semi-aggressive. Get at least a dozen if can. They are also fairly easy to spawn.

The albino ones aren't as attractive (IMO) and are harder to find.

rileynapalm i'd also classify columbians as semi aggressive. it really just depends if you give them a nice sized school or not. i've seen them get bullied by serpaes and then a few days later, the serpaes were doing the nipping (not unusual for serpaes btw). the columbian r/b tetras are very aggressive eaters though. kinda like diamond tetras. they're always the first ones to the food.

but i'd say if they've got enough cover, swimming space and a school of 5 or 6 you should do well.

BoxxerBoyDrew Colombians are very cool/pretty fish! I have never had either the Columbian or Blue, but every one I have asked about the blue says they can be nasty, depending on the size of the tank.

wicca27, That is a FREAKIN BEAUTIFUL AWESOME group of Colombians you have there!!!! I have been wanting to get a group of 8-10, but NONE of the fish stores, even the big box stores, get in any number of them at one time! Most only get in 2 or 3 and then 1 will almost always kill of the other 2! GRRRRRRR So hopefully one of these days I will find a good size group to buy!

wicca27 they probably would be i notice my columbians tend to stay closer to the top say the upper half of the tank. and as long as there is some cover/hidding spots for the head and tail lights it should be fine.

Nice plant! Thanks!
02-13-2013 04:57 PM
Blackheart Ahhh okay. I was thinking off adding a nice school of them to my tank, I already have a school so far of 8 head and tail light tetras. do you think they'd be fine together?
02-13-2013 04:13 PM
wicca27 no there are 15 columbians 6 angels (including one breeding pair) between 8 and 10 guppies, random guppy fry, 2 hill stream loaches, and a bristlenose. yeah i know its over stocked but they seem ok and i that is the 1 tank in the house that gets regular water changes lol.
02-13-2013 03:10 PM
Blackheart Is that all you've got in that tank is Columbian Tetras and Angels?

i love my columbian tetras once they got used to their tank they were fine and only go after each other from time to time. they are pretty aggressive eaters though and do tend to jump out of the water going after flake. makes me think of piranha when they eat lol. i had to drop the water level in the 55 down a couple inches below the rim of the tank so they wouldnt fly out. i have guppies in with them and they dont mess with them or the angels. they will eat guppy fry though.

Ashnic05 Blue Tetras I would consider semi-aggressive. Depends on the size of tank and the tank mates you put them with, but they can create havoc if not monitored. Great for larger tanks!

On a side note:
@wicca27: Picture #5 you posted with the white Angel....is that an onion plant in the background? C. Balansae? Looks awesome!

Bubba Shrimp I have blue tetra's and I would classify them as aggressive. They are a torpedo tetra and have a sharp mouth. They killed two Bloodfin tetras and a glass catfish. I have two them still in with Giant and Moustached Danio's. They can't killsthos haha but they are territorial still.
02-12-2013 01:10 AM
wicca27 you mean these hehe (columbian tetra) i love mine they can get pretty agressive with each other around breeding times and tend to fly out of the water at feeding time i had to put clear plastic wrap over the end of the tank i dont have a lid for cause i lost 3 out of the tank.





and they like to have their pic taken and tend to sneak into the shots lol

driftwoodhunter I have both. I love my Columbians, they are peaceful and have beautiful color. They shoal together well. I hope to always have some.

The Blue Tetras on the other hand, I'm not so sure about. In my community tank they are too aggressive. They are quite beautiful too though. They need to be in a group to keep their aggression to themselves, of so I hear. When I had my initial group in quarantine they killed each other. I lost one third in QT. I would like to try then again in a species-only tank.
