It's two and a half gallons! Even a pea puffer should be kept in a 10 gal.
Jumping spider, black widow, brown recluse, crab spider, or microcrab tank

Things that are way too large in your list:
1. Pea puffer
2 .Spotte Raphael Catfish
All of those get to big for a 2.5 gal, for example a betta needs at least 13 gallons, contrary to popular belief, this fish does not live long term in puddles lol.
Eh. I think it's kind of arbitrary to say that a betta "needs 13 gallons". Do they even make 13 gallon tanks? I have kept bettas in a 2.5 gallon before. I would recommend at least a 5.5 or 10 for one. But it can be done smaller IMO. But of course tank size is an opinionated topic.
But personally I think shrimp are your best option
If your not scared of salt, could do sexy shrimp in there

Pea puffers only get to about nickel size at the max and i believe that a raphael catfish would be a good candidate given that they barely move and are easily able to handle the water conditions if they start to go downhill in such a small aquarium.
True, but do you think a 5 inch fish is suitable for a 2.5 gallon?
Even the inch of fish per gallon rule (which usually brings up tanks too small for fish) ends up saying that's too small
The only scientific study i have seen on bettas said that they need a two foot planted tank to be happy, but if you were going into a random store to get one i would say it is more likely that an experienced aquarists keeping one in a 2.5 gallon would give it a better and longer life than the alternative
