Ok long story short, I had 2 kuhli loaches one died and now there's one left in my 55 Gallon that usually never comes out of hiding. But what I have recently noticed is this fish will wedge itself between the side of the tank and the heater. Now I'm not sure if it's cold or what, but the water temp is generally 77degrees.
Also I have 4 silver dollars(not bigger than an iPhone screen), 5 tiger barbs, 1 pleco, 4 tetras(lemon and redeye). So I was looking to add a couple of Bala sharks and pictus catfish, are they compatible?
And lastly I was given another 55 Gal
bow and some plants and drift wood. These things were used before so what would I have to do to add the driftwood b/c I tried driftwood in my other 55 Gal
and it brought the Ph down, then I started losing fish.
