I got myself a 5 gallon eclipse tank (the corner one not the tall hex one). and thinking of slowly putting a betta in there with some cherry shrimp and probably 2 single colour guppies (that way they don't upshow the betta to attack). right now i have two fake coral decorations with really cool rubbery tendrils that are soft and would move with a light current but i was wondering what do bettas like? i've heard they like tunnels and stuff so i'm thinking of getting a small black pvc pipe and cutting it in half to fit into the tank. my gravel is black too so it should be hidden easly. right now i'm wondering if it's a good idea to add maybe one or two stalks to tall fake green plants and also wanting to add a mini powerhead to the bottom of the tank to swish the coral decorations around for a cool effect. Would they like tall plants or short plants? and also would the power head be too much for the betta's swimming ability washing them to one side of the tank? the filter is on the hood which has a light current already. sounds like a whirlpool i'm running. any help would be great.
