Many kinds of hitchhikers? Looks like my tank is screwed

Zhugelaocunfu · May 1, 2023

Algae problem causes me to suffer after past 6 months and finally found out is my light is too long after chit chatting with in a fish shop. Anyway, recently the tank suddenly appeared many kinds of hitchhikers: a kind of algae,Vermetid Snail, one or two fireworms (At least looks like, it has white huffs, hates light but never appeared on coral tho) and an unknown blackworm has white tip. These hitchhikers make me feel like I am totally screwed:

The blackworm grows quite long and it likes to peek its head out from a hole:

And the algae looks like this (it has stem):

It can 100% feel like a loseing or never ending battle. Your tank is just sorting out its balance, with you to help. Very few hitchhikers will "ruin" the tank outright.

Vermited snails are ugly and annoying. Not overly harmful from my experience. The mucus stings can irritate coral, but in my experience it doesn't faze many if any. Maybe SPS?

Fireworms however are gnarly if that is what it is. I know the more commonly acquired is a bristleworm. Red and blue body, still will poke/sting you. Just not as bad. Technically they are a good part of CUC as they are amazing detritus/leftover eaters. I think they are spooky and icky lol!

Algea is probably the hardest to deal with depending on the type. Mainly nutrient control. And if possible somthing to outcompete it. Refugium/macro algea/turf scrubber/coral. There is also chemical fixes for some algeas but i believe it kills ALL algea.

Hopefully i helped some! I know someone else will chime in with more specific help/info ALSO post your tank size and parameters!! Always the first thing to include.

@trixter227 gave some good advice. Generally in my experience with the Fireworms I have in my tank they are not light sensitive. Bristleworms yes but not Fireworms though that may vary with each species.

Your algae appears to be Caulpera of some sort, possibly grape caulpera. This can become invasive if not maintained (either by hand or with fish) the issue is to be sure to get the roots as well.

No idea on the worm though. Hope this helps some!

Anymore info om the black worm. Size? Does the whole body move?

It moves but never get its whole body out of the hole it is hiding,usually its just the tip part peeking out of the hole,I would say it looks like those parasite hairworm (Gordiidae). my tanks size is 45cm^3(around 96L), light is 100W and turned to 40%, water test will be done after one to two hours (currently doing other stuff)

All of the parameters I have measured in my tank:
size:45*45*45 cm (96L)
salinity: 1.026
Ammonia: 0.1 I guess? (somewhere between 0.1 to 0.2)
NO2:0
NO3:0
PO4:0
temp:26 (my cooler is on so it will never goes above 27)

BTW here is an image of the fireworm like thingy in my tank:

It will instantly goes back to the hole once I point my flashlight at it.

Hello . I think it's peanut butter

Is the black worm slightly irridescent? The white part, is that a white band just behind the head or is the whole head white?

No need to freak out mate. Your algae looks like grape caulerpa as mentioned before, if you have or get tangs or a foxface this will be no problem.
Your fireworm is most likely beneficial rather than a nuisance, read this

About the black worm I can't say much, I had one in my live rock but didn't put it in my tank. Looked like a bristle worm though.

I find the more hitchhikers the better, more biodiversity. I had before and got again one or more mantis shrimp in my rock, I know where they are and keep an eye on them but the last one got to 2 inches in size and gave me no trouble.

Bristle worms are the ones that hide when the light is on.

Fire worms however will actually be out and about regardless of the time.

Hard to tell, because I can't see all of the antennae, but that looks like a eunice worm to me. Amazing color!

You need to get a algae scrubber like right away if you want to get rid of all that algae, it took me 3 weeks to completely clear my tank of all algae once i got the scrubber running, they are a total game changer

A white band behind its head

Typical marking of a eunice worm. They tend to stick to their holes and are lightning fast at retracting. Next, look to see if it has 5 straight antennae sticking out if the front of its head. Most are nothing to worry about, but can get big and freaky.

The problem of algae is that I can't find anything suitable one to bring in my tank:
Tang: my tank is only 100L,not a good size for one
Foxface: same

Yeah that is grape, love that stuff. I wish I could find it local.

Your hands are suitable, aren't they? Reaching in and slowly ripping the caulerpa out, trying to get the roots. You'll probably have some roots stay and regrow, but then you just repeat ripping them out when you see them. At some point the roots will get weaker and die off they can't regrow forever if you keep ripping them out.

You can use a stainless steel pick to chip away any roots, works like a charm.

This was my experience
