tetra ideas for 240 gallon

[mvh pets]

hi! 

im setting up a 240 gallon turtle aquarium, and my original plan was to have a lot of cichlids with  my turtle, such as 3 convicts, 4 severums, and a oscar,but my oscar sadly died due to a injury and i now want to do a tetra tank as i did not want to "replace" my oscar. i now have 30 silvertip tetras, with 4 serverums, and 3 convicts and a RES turtle. any ideas for more tetras with bold colors. BTW i have i 120 gallon sump as a filter

thanks!

Columbian blue tetra and black phantom tetra are really colourful

With that much capacity, and a large enough same-species group, you can observe fascinating schooling behavior. I would recommend well known schooling tetras, such as the Rummynose. Pristellas are really good schoolers, too.

Columbian blue tetra was a good suggestion, those look really nice all grown up. So do bleeding heart tetras.

One of my favorite tetras has always been Exadon paradoxus. They might eat the turtle though. 😛

If you want a colorful tetra you can't go wrong with serpaes.  Black neon tetras are another of my favorites.  Contrary to what you'd think from the name, mine aren't black.  The lower line is navy blue, and the upper one is sky blue that fluoresces when the light hits it.
