Critter ID from my fuge

[Kjames]

These guys are all over the glass in the fuge and seem to congregate near the light on the side. There’s a huge turbo snail that lives in there. Babies?

Flatworms

 

[Malifry97]

definitely flatworms

 

[Fishy212]

flatworms. Certain mandarins, 6 line erases and corris wrasses eat flatworms if you wanted a natural method of control. Most use flatworm exit. Will need activated carbon to soak up toxins when the flatworms die off.

 

[Malifry97]

Id use flatworm exit and LOTS of carbon

Those don't look like red planaria to me. I don't think there's a reason to medicate.

No I wouldn’t say so either except for the fact that the OP emphasized how many there were and from the picture there is tons. If this is indeed the case, that many of them can block light and irritate corals. Better to just get rid of them now before they cause an even bigger problem

I'd agree, if they were in his display. They're not, they're in the fuge. Which to me suggests there's something in his display tank that eats them or the display is otherwise inhospitable.

Two wrasses in the 90 gallon bare bottom display eat anything that moves. It’s mostly SPS with high flow. Continuous water changes and rollermat filter. Not a nutrient/detritus rich environment.

I saw one of these on the glass in the display a month ago. None since.

This population in the fuge has grown considerably in the last couple of weeks. They a very white, not red or rust colored.

I appreciate all the thoughts expressed here. The only pests I’m well-verses in are aiptasia (none in this build yet) and vermetid snails.

Acoel flatworms. They are photosynthetic which is why you see them near the light source. They are harmless in your fuge except that they will eat copepods. I have them but not near the numbers you have so I don't really worry about them. If I were you though I would siphon as many out as you can before you do the flatworm x if you go that route. They don't have a firm grip so in high flow areas you aren't going to see them. This also makes them easy to siphon out.

agree siphon out as many as you can,toss a 6 line in there ,at first worst area,then try to contain in seperate area of sump so he wont eat all your pods,toss him back and forth as needed,glad to hear not in display

 

[fishguy242]

have a pic of display,i am a stickhead to the bone,thanks

 

[vetteguy53081]

+1 on acoel. Although not lethal generate in high Numbers and can cause havoc in their own manner.
Net out ir vacuum as many as you can.
flatworm exit will get rid of them otherwise wrasses such as 6 line or lunare should also eat them

 

[Kjames]

Thanks, all. Think I will vacuum out as many as I can in the short term and add a six line. Minimizing the numbers prior to an eventual treatment seems wise.

Here it is. Tank is 8 months and going well so far. Baby sticks.

 

[fishguy242]

hope you can avoid chem treatment,wrasses are capable of wiping them out, have seen 75 reef w 40 breeder sump,got out of hand on me ,6 line in tank another in sump wiped clean less than a month ,top one jumped ,sump one disapperd ,no more flatties in that system for years after

love that chalice,also run all my tanks bare bottom,thumbs up

 

[eschaton]

If you insist on chemical treatments, I'd just go ahead and do it. Don't introduce a sixline, because it will eat virtually every pod in your fuge as well.

 

[HOOPDEEZ]

Doesn’t seem like an issue, maybe a food source

 

[Kjames]

Here's some video of some of them in natural sunlight. Surprising how rapildy they move. My display looks really great so I'm hesitant to do much more than physically remove them at the moment.
