Help! I'm afraid that my albino Dojo Loaches are going to be aggressive to my other fish!

[FishKeeper72]

So a couple of years ago I got a new dojo loach for my other 2 loaches. This new loach had red eyes, while the others had black. The new dojo go huge fast! He was like 8 inches long! When he got that big he started to harass my goldfish (he would swim right by them and cause them to try and swim faster to get away from him, it was almost like he was trying to suck on them). So I put him In a different tank (30 gal.). We then got 2 more dojo loaches for the aggressive loach to play with (the 2 new ones both had red eyes). The 2 new loaches grew big fast too! Now they are about 10 inches long! The 3 albino red eyed loaches live together now and are all friends, they get along great. But the problem is.... I got a new 75 gal. tank so that we could have just one tank instead of 2. I already put my original fish in my new tank, I just haven't put the 3 albino red eyed loaches in yet. I'm scared that they are going to harass my goldfish and cause my smaller loaches and plecos to hide. I'm also trying to find out if the 3 albino loaches are blind, because whenever I turn the light of the tank on or off, they sometimes suddenly jerk as if someone spooked them. They also go crazy when I feed them. Before i feed them, they are all peaceful on the bottom, but when they smell the food, they go crazy. Please help me out. I need to know what wrong with them, and if I should be worried to put them in my new tank.

I believe dojo loaches and goldfish are generally compatible; how large are your goldfish? Are they fancy breeds? These factors could determine a cause of aggression. Also, what types are your other plecos/loaches?

Do you turn the tank lights on or off when the room is in darkness? This stresses fish and the room should be light (daylight or electric light) for half an hour before the tank lights turn on and half ah hour after they turn off. If albino catfish are like other albino animals, their eyes are more sensitive to light.
The tank lights should also be on at the same time of day for the same length of time each day. Fish 'expect' this and we should try to provide what they expect.

This can be managed quite easily with a powerpoint timer like this, which will automatically turn the lights on and off at a set time, so you don’t have to worry if you’re out or otherwise busy.

GobyMaster's timers are what I use.
