I have a super heavily planted 10g with 9 neons, that has been set up for 2 years. I added 4 ghost shrimp of adult size (as big or bigger than the neons), and the neons ripped everyone apart within five hours. I watched the carnage as they were hit one by one. I tried to catch the remaining...
Last night I got about 6 neon tetras put them in my 20 gal high a month ago got 10+ neon tetras put those in a 5.5 gal.
I know I gotta wait to move the ones in my 5.5 to the 20 but how long?
Do I have to aclimate them to my 20 gal like new fish?
