Disagree.You have listed enough fish to fill a 150g tank, ditch the Salvini, JD's and swap the common pleco for a smaller pleco and you should be good to go.
I don't get it. Why would you say you just got the tank in your original post and then contradict yourself here? The question you should have posted is not whether you can, but whether you should. Yes, you can. No, you shouldn't, for the reasons given by other posters. It's good, sound advice. You should take it now rather than later, when the problems arise. And with your current stock, they will. Take it from someone who used to do the same thing.got a 55g givin to me the other day and i would like a little feedback on my stock list.
1x Salvini
1x Red Spotted Gold Severum
2x Jack Dempsey
1x Common Plec
1x Firemouth
I have one AC110 and one AC50 for filtration.
