Well mum is the word and mum has said no... Maybe she'll change her mind? I think pea puffers would be really cool though! Any tips, warnings etc. on pea puffers? Ive done basic research on them and it seems fairly simple. And of course she wants a somewhat filterless tank but...how do I do that? I know I need to cycle it and get tons of plants but the rest is beyond me! It's cycled and I do have a filter but she said it can only be on during the day. Will my puffers be ok without a filter and air stone during the night? I sure hope so... Otherwise I'm stumped on how I can have this tank at all. All advice is greatly appreciated!
