would give it a zero if i could
this is horrible. no fish should be put in a "tank" like this. it is far too small to house even one betta, has no way to filter, heat or even light. your fish will likely be sick or dead within weeks if you try to use this. the only real use for this tank would be to grow live aquarium plants to use in a REAL fish tank. remember: fish are friends, not decorations.
