What to do with a 2.5g Tank?

[MDK500]

I have an extra 2.5g tank that I just got done using for my Triops, it has a heater and filter and all that... I'll be keeping it on a windowsill where it will get direct sunlight. I know there's not much you can do with a tank this small but what are some idea's I could use it for? I was thinking maybe breed some very nice guppies or bettas. What do you guys think I should do? Feel free to be creative

i think a betta and some oto catfish

maybe a frog. i feel like if you put it on a windowsill it will have algae growing all over it in no time.

I know, I already have one in this window sill that will be next to it, it's a moss scape with Red Ramshorn Snails, Oto's, and Sparkling Gourami's. Algae growth is not too bad, probably because I'm running CO2.

Scratch the Heater and Put some plants (Maybe the Bamboo stalks, really not bamboo) Have a nice school of 6 Galaxy rasboras.

maybe some ghost shrimp on top of some of the suggestions above?

regardless of what fish you'd put into it (I'd keep it simple, go with a betta), I would make it a planted tank . . . take advantage of that natural sunlight, and should also help with algae problems . . .

Sump for a 5 gallon!
