I'm slowly getting organised to add a couple of Gourami to our 100L tank, I'm thinking a male/female pair of Honeys will be the new residents to move in with the Neon Tetras and Corys already there. I'd love some advice on making this aquarium an ideal environment before they move in. At the moment this tank has sand substrate, a big driftwood, floating Amazon Frogbit and a couple Contortionist Vals, as well as a handful of Indian Almond Leaves to slowly start the blackwater look. I've been having an issue struggling to get plants growing in this tank since changing the substrate, once that's sorted out I can start getting a few more plants back in there, if that's what they will prefer. I'd like some advice on things such as: Hiding places- do Dwarf Gouramis need hard-hiding places, ie, rocks & caves, or are they happy hiding in plants and behind driftwood? Water flow- do they prefer a still surface, like other breathers, or can the pick the calm bits of water between floating plants? I've got moderate flow and a decent amount of surface agitation, just wondering if I may need to adjust that setup in preparation for them. Plants- when I get my plant issues sorted and start planting for Gourami, which way should I head? Obviously they like floating plants, hopefully the Frogbit will have that sorted. Do they need a tank heavily planted with submerged plants as well, or are they happy in a leaf-littery, blackwater setup? Thanks for the advice everyone, having heard they can be a bit sensitive I'm keen to create an ideal environment before I add them, so I can just leave them be and won't have to play around in the tank too much while they settle in.
