Should I Replace Gravel with Sand?

Lol, good luck catching them. :lol:

As @Slaphppy7 said, it’s easiest to catch fish with two nets and when the water level is very low. Also removing any hardscape/decor also will help.
 
Easiest during a WC, when the level is low

Ah... Taking out the hardscape and plants means dealing with... The shrimp. I'm not saying that he scares me but I'd rather put my hand near a bear trap than root around where he lurks.

Well yes and no...you refer to mechanical filtration where particulates get trapped and removed from the water. But there is also biological and sometimes chemical filtration as well. In biological filtration for example, nitrosomonas bacteria oxidize ammonia resulting in nitrites and nitrospira bacteria oxidize nitrites into nitrates. Then with chemical filtration, sometimes materials or resins are used to adsorb impurities from the water (e.g. activated carbon). Plants do an excellent job of filtering as these extract nutrients (aka pollution) from the water and convert it into plant tissue, often eventually removed through trimmings.
So filtration is more than may meet the eye. :)
In terms of the way fish & other creatures feed, to my mind bamboo shrimps catch everything (filtering) while cories pick out the bits of food and get rid of the rest through their gills (sifting).
 
Should I put my corys and kuhli loaches (if I can find and catch the little wormy things) in the 54L tank for the time being? Just as a "sooner rather than later" thing?
Aren't you quarantining those new fish in the 54L now?

Kinda negates the point of a quarantine if you put any of your current stock in with them...
 
Oh whoops, yeah... I forgot about that!
:lol: All fired up for a new project and can't wait, I get it!

For when the time comes to catch the elusive fish, I found this video super helpful. I thought I was pretty good at catching fish, until I watched this and realised I had so much left to learn! Far less stressful on the fish using Cory's methods here
 
Make sure to get 2 big nets. Trying to catch little fish with two, 2 inch nets is not a fun experience. Trust me, I speak from it. :rolleyes:

Nice!! I'll give it a watch!

Not two nets, one large net.

One large net carefully angled, then herd the fish towards the net using your hand. :) Trust me, I speak from experience ;)
