I have been watching the little guy grow in my tank. It is not something I bought... hitchhiker?

is this something I need to worry about?

It’s hard to tell with so much blue. Any chance you can turn on your whites or try using a flash?

Looks like maybe blue sponge but really hard to tell from picture.

I used a gel... : ( I’ll take a better pic tomorrow during the day... it’s late evening here (I knew better than trying to take a pic this late)

the critter is blue... which didn’t help
