Rummynose and Discus

[legendaryfrog]

In addition to rummynose tetras, cardinal tetras are good candidates for a discus tank.

As for how many, 30 tetras would be adequete, and enough to make a nice school.

you could have a big school in there, even with discus. both like softer water, and rummynoses are tight schoolers that are to big to be eaten by the discus.

I have seen some rummies that are small. Just make sure that the ones you select are good size.

where a lot of people say discus need a lot of space they actually need to fill up their Tank space. By that I mean if you bought 10 2" discus they would be a lot more comfortable in a 30 gallon then a 55 gallon. I you got adult or semi adult discus you could happily house 8 in a 80g.
And Discus and tetras go great together, especially rummies since they school well it makes the discus feel safe. Other good tank mate are blue rams their calculated movements don't scare discus.

I keep rummynose (h. bleheri, not rhodostomus) with my discus, and all is well. Like others have said, if you select rummys that are decent size, you shouldn't have issues with your discus eating them. Out of all the tetras I have kept in the past, they are far and away the best schoolers... if this appeals to you, then go for it.

I never had a discus even the adult fish eat another fish even baby cherry shrimp or baby neons.
