Keeping My Boss's Fish Alive

[Yazikus]

Hello All!
It's been a while since I had by beginner tank crises, where this lovely community came to my rescue. No further upsets with my fishies- hooray!
However, my boss keeps a 95 gallon bowfront in her office. The Fish Lady (who helped me get my terrible setup) has a side business other than working at the lfs where she takes care of other people's fish. She is retiring this December. I am going to be the designated fish caretaker since the office heard all about my research after my debacle at home. I am going to need lots of advice!
My main question is regarding water changes. The tank is a long hallway away from our kitchen sink. What percentage and how often would I need to change, and how on earth would you do a change like that? I'll be appreciative for anything you might be able to offer.
Thanks!

what is that tank stocked with?
normally at least 50% per week is the rule but given the circumstances
you may have to look for compromise. If the tank is lightly stocked you might get by with less
that 50%.
As for the long distance I believe that there are python water changers up to 30 m(100ft)
in length, or else you could just do things the old-fashioned way, with buckets that have no limit to how far you can carry them with exception to how much stamina you have...

How does The Fish Lady change the water? First you are going to have to start testing the parameters of the water to help determine how much water needs to be changed each week. You will need to change enough to keep the nitrates at acceptable levels each week. If you don't have a Python or similar type water changer you will have to use buckets... Pretty simple really.

I'm not sure how the Fish Lady does it now, I'm going to stay after work hopefully one day and watch her. I'm almost scared to say what it is stocked with, but here goes. There are 4 fancy goldfish, 1 parrot cichlid, 2 new cichlids, a big pleco and what I think is a small pleco (about 2 inches, bright golden color, bottom feeder, with beautiful fins) and some snails that I couldn't find just now.

Like I said, start testing the water parameters and that will tell you how much water to change and how often it needs to be changed. It's a 95 g tank and the stocking might not be so bad really, depending on the types of fancy goldfish and cichlids that are in there. The biggest issue may be water temperature requirements, but many fish can tolerate a wide range of temps.

I was thinking it was like the tank of doom what with cold and warm water fish in there. So that is nice to hear.

I'm sure The Fish Lady does just fine with whatever she uses. I've been in many offices which have large tanks and someone is doing a fine job of keeping those tanks looking nice - they all have similar fish to what you have in yours. As as been stated already, goldfish are considered cold water fish but they tolerate a wide range of temps. It's good to get a liquid test kit and either watch her to see or contact her to ask how she removes water.

So my boss's big blood parrot cichlid is chasing around the new little cichlids, should I be worried and is there anything I can do? The big one is as big as a grapefruit (for lack of better comparison, obviously not all the way around) and the little guys are a little smaller than a cupcake top.
