The first fish should be a very sturdy species such as the Neopomacentrus
cyanomos, the Regal Demoiselle, they are adapted to survive in a wide range
of parameters fluctuations. Any damselfish is fine but I found this species
to tolerate better than any other.
For starter they are great.
In following replies to your post the Lawnmower Blenny was suggested but
after a few years experimenting with controling nitrates naturaly in my
tank, I found that vegetarians contribute more to increase levels of
nitrates in your tank.
You see, the nitrogen cycle changes ammonnia to nitrites, both toxic, then
the nitrites get transformed to nitrates. On this stage is when nitrogen is
less toxic and easily absorbed by algae. If a Blenny is to eat the algae,
it gets transformed again to Ammonnia and the cycle starts again. The best
way to get rid of unwanted nitrogen in your tank is to harvest algae
manually not to have the vegetarians turn them back into the cycle.
Blennies are great fish and will eat almost any flake food. I have to keep
a refugium where I extract the algae myself.
Another sturdy species is the Clarks Clownfish.

Hi,

I was wondering whether anyone has a suggestion for a cool first fish
to add to my sal****er tank.

This is my first SW tank, having kept small and big fw tanks all my
life. Tank cycled for a month, and i started added critters last week.

The current inhabitats are hermit crabs (10 red legged), snails (1
turbo and 5 bumble bee), and an Emerald crab.
I had a surge of algae a week after my tank finished cycling, and am
trying to get this under control with these cleaners. I would like to
add fish soon.

My near-term goal (next 6-months) is to add 1 clown fish, 1 goby, and
1 six line wrasse.

I thought it would be a good idea to start with a reasonably priced,
hardy fish to start.

I have 50 lbs of live rock in a 58g. all my nitrogen params are
stable, and where they should be.

Temp is 82, ph 8.4, alk 2.6, calcium 450.

If you have any suggestions, I would be interested in hearing friom
you.

Thanks, Aroon
