You have so many empty tanks! Can I have one? 😂. Yeah I have had a guppy in my 29 gallon for a few weeks now and I am thinking that my betta is much better off in the 2.5 than he would be. He is so fast. I am also going to get him some friends soon.
2.5G - 1 female betta: "Miss Cleo"
5.5G - 1 betta: Half-moon King "Cobalt"
10G (with 4G of water) 1 female betta "Grace"
29G - 1 gold marble angelfish "Bartholomew"
1 Male fancy guppy "Guplet"
