I'm looking to set up a tank and was thinking of a mini out and out predator tank but after speaking to my local fish store they said it would be a really hard tank to pull off. Obviously he is busy and can't get back to me for a while so I was wondering... What if I was to choose one out and out predator of about 4" (6 at the very max) and the others that are more insectivorous or omnivorous like the Golden Wonder variant of the Striped Panchax, A Giant Betta, some.relatively large Tetras (2-3") and a couple of smaller sized Offers, I do realise the Puffers would be unlikely to pull off with this one but would be good if it could work, I would have said specifically pea Puffers but they may be too small. What type of tank size am I looking at and does anyone have any suggestions of fish that are insectivorous or omnivorous but would leave fish alone too large to fit in their mouth but would take smaller fish if given the opportunity (and no I'm not gonna feed them fish, it's just I like to have as near to the mini predator tank I wanted only I was told.it wouldn't be practical) These all have to be able to thrive in softish water.
Thankyou.
Thankyou.
