Ah ok! Thank you, I will definitely go with a lid then.It is generally a good idea to have a cover on an aquarium with fish. It reduces/eliminates dust settling on the surface (which can cause issues), it avoids evaporation from condensation (which not only reduces the tank water, leaving behind the bad things, but it gets into the walls of the house), it prevents fish jumping out (you might be surprised how many fish will jump at night from this or that, even cories), and it can avoid dangerous substances accidentally getting in the water. It also keeps the air above the surface warmer, and with anabantids this is very important.
Ohhhh ok. I have 3 AquaClear filters, with adjustable flow, and as far as I can tell, they cause VERY little surface agitation, and gentle water movement inside the tank. I have both an AquaClear 50 and a 20 to choose from, and I have definitely noticed on my 10 gallon that there is little water movement much to the side of the filter. It is hard to explain, especially as I am not able to put up a video. I will definitely keep an eye on it though, and can run to Petco in a pinch If the HOB doesn’t work out! I appreciate your help!I don't like HOB filters (had them years ago), there is too much current, though I've no idea if these newer models can be reduced, but the waterfall design is not suited to what you're planning now.
Do you you think the stocking sounds ok, or are there any noticeable problems?
