one of two Black moors is much smaller and sits on the bottom of fish tank #1
Hi Guys.
I am new here, so please don't be harsh...

So, my fishtank is the LoveFish Panorama 64 ltr tank. Some plants are there as well.

almost two years ago (I think) I bought two small black moors.
Now, I have noticed that one of the moors, for a month or so, spends his time laying on the tank bottom almost not moving, with the fast "breathing", with only very occasional swimming (mostly at the bottom of tank, with occasional swimming to the top of the tank, breathing in from the surface and then sinks dows and releases the bubble.

Another one is perfectly fine, is actively swimming, eating and is SIGNIFICaNTLY bigger - almost twice the size of the first one. Now it started to push the first one, like, wanting it to swim more...

I had 2 shrimps and 3 Danios in tank earlier, but shrimp managed to live around a year or so, and danios died one by one with few months gap between them after half a year or so...

I am checking water with strips (I know...) and it does not shot any bad signs of amonia poisoning.
I will do water changes of 20% every few days now to see if there's gonna be any improvement...

So, guys, anyone have any suggestions?

Sorry to read about one of the moors (and, previously, the danios) not doing well. The immediate issue which springs to mind is that the tank is not an appropriate size for them - ... -size-life-expectancy.htm ... esheet.php?caresheetID=50 [black moors] ... esheet.php?caresheetID=20 [danios]
This is very likely to impair water quality - ie not be able to consistently keep it at 0 ammonia, 0 nitrite and 20 nitrates (or no more than 20 above whatever your tap water nitrates level is) - which, in turn, will affect your fish, with the weakest succumbing first and the other(s) likely to follow suit afterwards if this is not addressed.

Aside from upgrading to a larger tank ASAP (second-hand tanks may be found on - a 240-litre tank is a great size and shape of tank for goldfish), I'd advise:
* improving water quality through daily water changes - closer to 50% rather than the 20% you mention - plus following the advice on ... ammonia-nitrite-spike.htm ought to help;
* buying a liquid-based test kit, especially for ammonia as the strip versions are difficult to read;
* pre-soaking food so that it sinks, to prevent air being taken in and potentially affecting the swimbladder (the buoyancy aid), and feeding with chopped pea once or twice a week instead of flakes/pellets.

Hope that's helpful and sorry for the late reply.
