Ghost shrimp and snails arent for everyone, so try not to discourage anyone from trying it, it is worth trying, ghost shrimp work great in mine, and snails work great, i had one before. But im sorry that u didnt enjoy it, when you get a bigger tank you can add some more fish as tank mates, sorry for your experience hope what you try next works out.
10 gallon tank
Fish: Male veiltail betta, Chinese algae eater, one Pleco, 3 Ghost Shrimp and 3 Zebra Danios
Fish: Male platy.
Rest in peace to jaws the rts, and bubblegum the betta
