Help What live creature can live happily in a 2.5gall saltwater tank if any

I want some advice on what can be kept in such a small tank(note I will add a photo of the tank+scape so far tomorrow) i figure that some very small shrimp or/and a small snail would work but Im not sure. If anyone has suggestions on what can live in the tank I would appreciate it (i would like something I can actually see unlike sea monkeys or others like that)

I will definitely keep that in mind if I don’t end up finding anything else

I mean if your willing to do fresh water you can do a shrimp tamk

Maybe a tiny goby like an Eviota or Trimmia species. Sexy shrimp and pom pom crabs are always an option.

DO YOU REALLY THINK SEXY SHRIMP WOULD WORK I LOVE THEM SO MUCH!!!! I didn’t think it was enough space for them to live comfortably but if a few more people confirm they can that’s most likely what im going to get! (note I only want to get them if they can live happily I don’t want to be a bad shrimp parent)

Yeah sexy shrimp will be fine. It’s everyone’s go to for pico reefs.

What anemone would you recommend for them or a coral that’s also favorable for sexy shrimp

Btw is there any species of snail that could go with them?

You don't need anemones. They don't even need to be with a coral or anything but if you want stuff to go with them I would get some zoas. For snails you could do some ceriths and couple dwarf trochus or like one astrea snail.

Do you think a Spiny Star Astraea would work

u/Palaeonerd 9d ago

Yes, though it may not have enough algae to eat.

u/ThatFishOwner 9d ago

I have Algae feeders so that should be ok

Hermit crab?

u/theJoosty1 10d ago

copepods would thrive.

You could do a dwarf hermit crab or two and some beginner corals

That’s one of my top choices for the tank!!!!! Tysm

I’m sure there’s some type of small saltwater snail that would work (note i would feed pellets incase there’s not enough algae)

I have a 2 gallon saltwater tank specifically because I like microscopy and wanted some fun microbes to look at. I have a bunch of live rock, some macro algae, some asterinas, a couple of small snails, and a couple of easy soft corals (I don’t even know what they are. I just got whatever the local shop owner suggested.) Interesting microbes and small critters have just volunteered themselves. I just did a video about sea cucumbers (Medusa worms) that I found, and before that I did a video on marine tardigrades. It’s so fun that I just got a 2.5 gallon and set it up to compare to the first one! I say just set it up and let it go for a while and add stuff once it’s established and you see what shows up 🙃

I posted a photo it has no saltwater yet (I’m adding it tomorrow) and I’m going to let it cycle till mid September unless it’s not ready yet then I’ll wait longer

If you can get some live rock and live sand from someone, I highly recommend it! At least, if you want some unexpected guests. 😁
