blackwater tank cycling?

A window into my 95 (48x24x18 in ineches l,w,h):

Someone told me that ruby tetra would hide all the time but i can always find 15 or 20 of them in there so not sure why others think they hide.

A few more:

The ones above don't have a lot of blue - and i was doing water changes on the basement aquariums today and i noticed the rubies down there have a lot more blue on their fin - this is a weak example but they are rater disobedient when i ask them to pose for pictures:

Hum. Mrs google suggest it has to do with lighting and not the actual fish - interesting because some of them have a whole lot of blue. This aquarium is a bit more open then the one above that is the 95.

Oh well you or at least I learn something new everyday.

Hi all,

I don't know, I bought eight, I was down to three at one point, and now have about 15. They have never shoaled, they've always splintered into the jungle, where they hold pretty much motionless in their spot.

Some mosquito larvae really get them going, but they tend to spar with one another, even at that time.

Mrs google suggest it has to do with lighting and not the actual fish - interesting because some of them have a whole lot of blue.

Same for me, I'm pretty sure it is the fish, some of mine are deep red with prominent pale blue flash, and others are much paler all around.

I wouldn’t be surprised if there is local colorforms of these aswell.
It could also be a hierarchial thing within the group, i guess.

Just guessing.

Is a ruby tetra different from an ember tetra? What’s the proper name?

Yes, Axelrodia riesei. Ember Tetra are Hyphessobrycon amandae.
There isn't a lot of data about Axelrodia riesei - <"https://www.aquariumglaser.de/en/09-characoids-tetra-relationship/axelrodia_riesei_ruby_tetra_en/"> & <"https://www.tomc.no/fish.aspx?fishIndexID=1957&gruppeID=2'Z>.

Is a ruby tetra different from an ember tetra? What’s the proper name?

very different in looks and behavior. Mine tend to be a bit more active then ember but not super active - they are also slimmer - more red then orange and have black spot near the tail. My understanding is ruby are more sensitive to water hardness - since i've always kept mine in near blackwater conditions i can't comment on how adaptable they are to harder water.

I prefer ruby because they are a bit more active then ember and will quasi school but not tightly school - i will say collect together. Also they will show a lot of boldness at times that ember lack. They have no problem trying to steal food from my krib frys something ember would never do (my krib 'frys' are now nearly the size of the ruby tetra so not eactly frys per say).
