The ghost shrimp are going back to the pet shop lol. I just bought them to have "something" in the tank until my pumpkins arrived, then they got bumped over to the 2.5 gallon... now they're getting bumped back to the pet store lol.
I'm not a fan of sand either unless there's some very heavy sand I can buy, the last I bought floated a lot at first and was a pain in the ass to clear out and get settled down. Fine now, but it kind of made me lean away from sand.
I keep seeing some kind of granule/pebble type substrate in a lot of tank pictures. I've seen black looking nuggets of sorts and brown rocky looking things, just have no idea what they are. Some kind of neo will go into the tank along with flame moss, a few little plants and maybe an erio.
No ghost shrimp though.. I have one that is super cool and active but the 2 females are about as boring as you can get. The day I got the pumpkins and saw how they act, I knew the ghosts were gone lol...
