my brother came home and surprised me with a mudskipper today and i have no clue how to take care of it.
it came with the sticker "periophthalmodon septemradiatus asian mudskip" on the bag but im not sure if it is.
i have a night class in a few and i have no time to go get the proper salts and substrate or even take a pic (i will when i come back though).
will this little guy survive till tomorrow in a 10 gal with FRESH water up to its shoulders
or is getting the salts and proper substrate an immediate must?


Thanks
