Kuhlies are about all that would work in that tank, and even then I will suggest it may not be great.
Loaches in general prefer much more water movement than flat sided fish like Angels. Angels are not built to live in fast moving rivers; most Loaches come from such rivers.
Do some research here at Loaches and look up each fish that you are asking about. Look at optimum temperature range, and adult size.
Here are some notes about the fish that you have:
Angelfish: Warm to very warm water, low water movement, soft, acidic water. (Hatchery raised fish can tolerate harder water)
male Swordtail: Warm water, average water movement, hard, alkaline water. Salt is optional.
Ruby Shark: Reaches 6" (too big for a 3' tank), aggressive and territorial about caves (mostly toward other shark shaped fish, but I would not risk other bottom fish with this guy in there), cool to moderate temperature.
Whiptail cat: Many species. Generally prefer cool to moderate temperatures, more than average water movement. Many come from moving water, streams and shallow rivers
Bristlenose Pleco: Cooler water. Males can get territorial about a cave, especially if there is also a female BN in the tank.
Clown Pleco: A wood eating fish from somewhat slower moving moderate to warm water.
a small school of red & blue Columbian Tetras: Warm, soft, acidic water.
Cool temperature = low 70s F, low 20s C.
Medium temp = mid 70s F, mid 20s C
Warmer water = uppermost 70s to low 80sF, upper 20sC.
I think your tank is already pretty full.
If you want to trade in some fish with the goal of getting some Loaches I would get rid of the shark, the Angel and a couple of the Loricariads. Make sure there is enough water movement to circulate the water at least 10 times per hour.
Kubotai Loaches or Kuhlies are small enough to work in this tank, but not with all the fish you have in there now.
38 tanks, 2 ponds over 4000 liters of water to keep clean and fresh.
Happy fish keeping!
