Centerpiece Fish Ideas And Opinions On Stocking

    Hi guys and gals!

    I am deciding on a centerpiece fish (or the possibility of one) for my 20-gallon high tank. It is fully cycled and has a good amount of plant life with more to come, which should help remove nitrates. I am running an aquaclear 50 along with a small penn plax bubble filter that I modified to hold aquaclear bio ceramic for adding filtration.

    Currently, it is stocked with 8 glowlight tetras, three albino & four juli corys, and two oto catfish (the small algae eaters). There were 5 cherry shrimp but they are currently MIA (either hiding or did not survive being added. I am planning on adding malaysian trumpet snails and ramshorn snails to help keep algae in check and keep the substrate mixed to avoid anaerobic pockets. I do understand that adding snails will add to the bioload.

    I have tried dwarf gourami and like the look but the petco near me has bad stock and the one I bought died (all tests came back zero) and when I went to get my money back I checked the others and they all looked worse for wear.

    I am considering trying another Dwarf Gourami (I like the blue kind, not a fan of honey), but have also considered a blue ram or an apistogramma. Thoughts on these options?

    Does anyone have any other centerpiece fish ideas? I am also considering loading up on tetras and just having a school of 15-18 glowlights.

    Your tank is more then fully stocked already, add the snails if you want but dont risk adding more fish.

    Do you change water every day? That is a lot in the tank. I would say that the floor is already pretty full, so dwarf cichlid might get crowded. Gourami might fair well. If you stay on too of changes and have a low water movement. The overstocking Will add co2 for plants to flourish.

    I change the water once a week (around 30% total volume) and my ammonia, nitrites, and nitrates consistently test at zero. I think the heavy use of plants as well as the oversized filter help to keep things at such levels. I am pretty sure I will be rehoming one species of the catfish and sticking with just 5-6 of either kind since I have decided I want a pair of Apistogramma, specifically A. Borellii as they are much more docile. I have decided against adding snails since algae seem to be nonexistent for the moment and I don't want to add to the bioload.

    I know that the apistos will stay towards the bottom, so I am planning on minimizing the cory population to just 5-6 of one species. I'm attaching from aqadvisor my current set up (including the apiostos which I do not have yet) to give you a sense of the stocking level.

    I personally think you have space. Especially if you don't add the snails. You have a lot of lower level fish, so what about getting a pearl gurami, or maybe two? They prefer to be in pairs. Or maybe a blue gurami.

    I personally wouldn't add anymore fish too. But if you really want to, I'd say a honey gourami. They dont have the issues dwarf gouramis have.

    A pearl gourami would get too big for a 20 high. I would try another dwarf gourami or maybe a betta

    If you add apistos to this tank you are killing your cories. you might as well be chopping them up and serving them on a dinner plate. Get a 40 gallon breeder, and it might work.
