Paludarium idea

[reddead38]

Sorry then but a lungfish WILL outgrow that tank and WILL eat your archerfish and anything else a smaller more manageable fish would be a ropefish (35-50cm long)

I have kept them before and I know how big they get that's not my issue as Iv got other tanks I can always move it to. Iv also never had an issue with an SA lungfish being aggressive enough to go after other healthy fish.

If it's a risk you want 2 take go for it, your tank but archerfish are not active swimmers they stalk and that would be very easy for a big lungfish to get in a 4ft aquarium, but like I said your fish your tank do what you want
