New school of green chromis

4

15 days up and running, the chromis are still alive! Ammonia and Nitrite are 0 and Nitrate is at 15. This weekend, I added a bunch of macro algae and a tank background. The rocks and some of the sand are beginning to turn orange/brown. In 2 more weeks I hope to add some snails and copepods.

Uronema or Bump Injury or Other?

I’ve had a trio of Chromis for 3 months now, all eat well, swim together, but sometimes chase and nip at one another. In addition they have a habit of backing into holes where my royal gramma hangs out, where they will swiftly be chased away.

A red dot with a white center has appeared on one of their tails, that appears to be more pronounced on its left side but still visible on the right.

Is this early onset Uronema, a bite / bump injury, or something else?

I’ve got two questions.. one, I can’t get any good pictures of my tank because the light interferes with my camera.. Any fixes to this?? Two is stock.. I have a 55G long aquarium with a 20G sump. I currently have as follows

X2 clowns

X2 blue/green chromis

X1 Royal Gramma

X1 Coral Beauty

And a few inverts (snails, emerald crabs, and pistol shrimp, couple corals)

I am going to get a green mandarin at some point in the near future once I can successfully supply its dietary needs. And a yellow watchman if I can ever keep them from getting into the sump 🙄… I want to add maybe a fire fish or 2 bangaii and be done! Is that way too much? All my current fish are happy and the CB just got out of QT and loves the tank! What do yall think?

Looking for suggestions on beginner friendly fish and corals to start adding. Tank perimeters have been stable , tank is over a month old. I have not hit “the ugly stage” but I had a couple of very mature live rocks from day 1 in my tank (the 3 on the far left). I read with seasoned live rocks the ugly stage can be prevented or severely less (not sure it’s it’s true or not but not getting my hopes up) I do not have a clean up crew right now, LFS has said it’s to early to add as I don’t have any algae in my tank yet. I have had some orangey looking algae grow on the back of the plastic cover and on the output nozzle

Currently have:

2 black and white clown fish

1 green chromis

1 blue springer damsel

Corals:

2 toad stools

1 GSP

Update: Added the following livestock since last post… last couple weeks fighting off Diotom blooms or the like. Weekly 10g water change and maintaining the glass clean. Don’t really disturb the sand or rocks.

2 Ocellaris Clowns

1 Royal Gramma (very shy)

1 Powder Brown Tang

1 Fire Fish (not in video)

4 Green Chromis (not in video)
