I'm glad you said that! You can't keep these fish together in one tank like someone mentioned. Here is the deal with the fish your picking. All of which I have kept. the gibbus would be fine sectioned off in a 2ft piece although you won't get much personality out of him cause he would like to have more room to swim. Altuvie same thing.. the elong.. they need a longer tank.. they like to dart around your tank, so a short tank will cause the fish to run into the tank which hurts.. so he will lose his character and sit still most the time. so do you have enough gallons for these fish with what you mentioned.. yes.. do you have enough tank space.. probably not.. best thing to do would be get the gibbus and Altuvie a 40b and get the elong a 55g. As the fish age (probably 3 years or so) move the elong and gibbus to bigger set ups. Altuvie will probably be fine.I want to get one big tank and build fiberglass dividers to separate them, what size should the tank be? I was looking at a 135 gallon(72''x18''x25'' tall).
