first saltwater aquarium, weird 15g setup, many questions

ooh are more critters gonna pop up that will clean it?
Some detritivores may eat it. Or, a small increase in water flow (a gentle flow) would help as well.

Those bristleworms are part of the clean up crew. Those, IMO, are the good ones. Back in the 90s we thought they were bad and recommended trapping/removing them. Then, we learned that they are actually beneficial. I actually introduce bristleworms into my tanks if I don't have any from live rock.
 
i figured it out, a pipette with the tip cut off did the job!

it even got that green macro algae clean without damaging it at all. the reason i decided to try cleaning it again is because the algae was starting to get caked in nasty and its growth was slowing.

speaking of which, i think i have some red stuff growing on this one rock, possibly a couple species. one kind looks stiff, resembles a tiny branching coral, and hardly grows at all, and the other is noodly and grows much faster.

also the coralline algae seems to be taking to the dry rock!

there's a lot of things happening on the starfish and anemone rock!

A: these are actually on several rocks, but i keep forgetting to ask. pale, closed-ended tubes. what are they? they're stiff and don't sway much in the current. i don't think anything lives in them. the ends of some of them are becoming very thin and threadlike.

B: fuzzy green algae. it seems chill.

C: very new, they look like fronds or feathers.

D: slimy red algae. it seems gross.

E: hard, plate-like growth overtaking that sponge/bryozoan colony. maybe just the coralline algae growing?

F. a new sponge species seems to have popped up.

G: orange tunicate? it's been there since the start, slowly growing. i've never seen anything pop out, i think that is just the animal itself.

also, as you can see, we've got a brown filamentous algae thing going on. the same kind is on the glass, filter intake, heater, pipe... any surface. the copepod population is booming, hopefully they'll take care of it.
 
i'm compiling the next batch of stuff i need!
so far on the list:
- tests for KH, magnesium, and calcium.
- marine snow? i have been somewhat regularly feeding the hitchhike inverts with crumbled fw flakes, but that's probably not what they need.
- food for the ✨green clown goby✨ which seems to be mostly frozen mysis?
- all-for-reef
- smatfarm 30w reef light
- a tiny powerhead for the 5g
- maybe a PAR meter bc im curious
- chitons, and the ✨green clown goby✨ itself. i'm not sure where i'm going to acquire them. everywhere online seems to be out of stock!
 
Test kits - Sounds good
Marine snow or phytoplankton - IMO, not really needed unless you have filter feeders.
All for Reef - I have not used it personally but, have heard good things about it.
Smatfarm - Sounds like a good upgrade.
Tiny Powerhead - Look into Hygger on Amazon.
PAR Meters - These need to be completely waterproof and are specialized and pretty expensive.
Livestock always seems to have less availability during the winter months.
 
things are happening! i'm so happy!
i went to throw out some old, heavily damaged tanks, and a background was still attached to one of them, so i removed it to put on this one! it's blue, but it looks very dark behind the tank. i wasn't sure if i wanted to get a background at all or not, so i didn't buy one, but this does look a lot nicer. i might make a simple one for the 5g, out of a black garbage bag.

and yeah the algae has spread to the front glass. it's like it's swirling around the tank... it was on the back, and then disappeared and went to the left pane, and now is on the front.

also the copepods are moving into the tube, and some are in the 5g! there's even a little algae in there, despite it not having a light yet (i'm going to move this current light onto it once i get the new one) and i'm just really excited that this weird system is working! life is starting to spread over on its own!

how do we feel about a pink-streaked wrasse? they're much more expensive, so i probably wouldn't get it at the same time, but it's one of very, very few species that:
- is not a goby or blenny (because those might fight with my clown goby)
- is not aggressive in general
- is reef safe
- will take frozen or prepared food
- can live in 15 gallons
- i like the look of
