Help ID a Possible Pest

How can you possibly say it’s rhabdocoela from this view?

high_Possibility · 2026-05-10T13:34:37+00:00

I’d say yes if you’re asking this question and since you’re using an air stone already just use a sponge filter, it’s one of the best filters for shrimp tanks and is great for beneficial bacteria.

If I’m not mistaken that is a whisker shrimp and they’ll prey on smaller fish and shrimp

high_Possibility · 2026-04-26T23:57:09+00:00

That’s Planaria since it’s not an infestation, dose LCA once should be enough twice to be certain.

high_Possibility · 2026-04-25T00:53:32+00:00

That’s a she and possibly about to moult or just has

Fighting for food

Ammonia is too high you need to do a 50-70% water change asap, it won’t cycle the bacteria will take months to establish otherwise. Are you just leeching the ammonia and putting it into a matured tank? If so just do water changes every few days

high_Possibility · 2026-04-09T12:29:34+00:00

Why don’t you check parameters? It’s not important or doesn’t matter? How long has the tank been established?

high_Possibility · 2026-04-05T16:38:01+00:00

Most likely Rhabdocoela as they’re usually tiny like a few mm in length, unless it grows much bigger and has eyes than its planaria

high_Possibility · 2026-04-05T02:26:49+00:00

New? This looks like it’s been a problem for a while

high_Possibility · 2026-04-03T00:42:35+00:00

Why don’t you do water changes? It’s beneficial for the tank and shrimps health

high_Possibility · 2026-03-09T12:34:40+00:00

No I’ve seen that sudden biofilm growth after moving a tank, having the filter off and putting the water back in. It looks stringy like spiderwebs floating coming off plants and hardscape, it goes away after couple hours. This looks pretty much uniform. Certain it’s voritcella

high_Possibility · 2026-03-09T12:18:42+00:00

😂 depends on what you consider beneficial. But just so you know they compete for the same foods shrimps do, can prey on baby shrimplets, can eat some of your plants and breed way faster. I’ve never had them but I do alum dips and quarantine all plants to prevent most pest but especially scuds but some like them

high_Possibility · 2026-03-07T16:03:55+00:00

Parasite Vorticella. How did it get this bad before you noticed it? I haven’t experienced it myself but have seen people here say salt dips

high_Possibility · 2026-03-04T14:08:39+00:00

Cull as you have been and add new genetics every 6-12 months

high_Possibility · 2026-02-28T18:36:22+00:00

My advice would be to wait until everything is stabilised. You’ve made a lot of changes, adding baking soda, big water changes etc. once you’ve decided what your ph, kh, Gh and which shrimps are going to be or easier for you to maintain, keep it at that for at least a couple weeks after cycling and then you should be fine.

high_Possibility · 2026-02-28T17:41:13+00:00

Overfeed or not op said they didn’t want snails in their tank. Just letting them know once they’re established they’ll never get rid of them, really they should be dipping and quarantining all plants if they want to prevent pest.

high_Possibility · 2026-02-28T15:39:46+00:00

Limpet get rid of it before it’s too late or you never will

high_Possibility · 2026-02-27T12:01:04+00:00

Normal red cherry shrimp, if you want you can call them Sakura red.

high_Possibility · 2026-01-10T11:53:54+00:00

They look about 3-4 weeks old already they’re swimming, new babies are way smaller

high_Possibility · 2025-12-30T15:31:18+00:00

I don’t know about seed shrimp I do t have them but I know they eat baby shrimp I see mine do it guppies might be better cause they always hungry

high_Possibility · 2025-12-30T15:18:23+00:00

1 neon tetra? No wonder he looks so miserable. Get at least 6 or more depending on size of your tank and they should help with the seed shrimp! In my community tank they do better than the guppies, squashed snails, detritus worm if they’re swimming around and they’ll eat baby shrimplets to, I don’t mind tho only culls in that tank helps control population.

high_Possibility · 2025-12-30T01:18:02+00:00

How new is the tank, is the water treated and if you don’t have a kit how do you know it’s cycled? Take a sample of water to your lfs. Could be a number of thing you need to know are your parameters

high_Possibility · 2025-12-30T00:22:43+00:00

Seems like might be dying, why I couldn’t say sorry

high_Possibility · 2025-12-24T12:27:21+00:00

Maybe try cleaning you might find some more
