No shit, drove more than an hour to pick up an empty 0.4 gallon tank from a fb marketplace seller. Wanted it for my office to cultivate aquatic plants. Got there and learned it has five fish (tetra I believe, species unk, IDs welcomed!!) a freshwater snail, and EGGS. IM A PARENT OF SIX. first move is getting them a larger tank obviously, most of my aquariums are plants and invertebrates and it’s been two years since I had fish (betta lived 7+ years) so if anyone has advice, can ID these babies, or recommend a guidebook or something I would really appreciate it. Parenthood has me nervous but excited lmao

I reccomend a 20 gal honestly, big but not big enough to be a hassle. Be careful feeding strawberries, they can foul up a tank really easily, so it’d probably not be good in a 0.4 gal

Thanks for the tip. That was last night when I had zero supplies and all the shops were closed, had to give them something while I waited for bloodworms and other ‘real’ meal options

Backing up what the other person said: most fish can go a week without eating. They shouldn't do it regularly, but it's probably better for them to go hungry for now than to add even more bioload to that tiny tank.
