I have a 30 gallon tank that has been established for over 6 months. About 1 month ago I noticed algae growing in my tank. I thought it was strange because I do regular water changes and had never seen algae in the tank before. Everything else seemed fine so I figured I would go buy some "algae eaters." I purchased 2 rubbernose plecos from the local store and added them to my tank. For the next week or so everything seemed fine. My fish were acting normal and healthy. About a week ago I found one of the plecos dead, and 2 days later the other one died. After that, some of my fish were acting very lethargic. The mollies and swordtails would just sit at the bottom of the tank. They would move around sometimes, but not like normal. The 2 Gouramis in the tank seem very healthy and normal. In the last 4 days I have lost 1 molly, 1 striped raphael catfish, and a snail.
It looks to me like the catfish and swordtail may have ich. I can faintly see little bumps hanging off the edges of their fins. They do not have white bumps on their bodies though. The other 2 gouramis and 2 mollies do not look like they have ich, although the mollies seem less active than they used to be.
As I said before it is a 30 gallon tank. Before all this happened there were 2 gouramis, 4 mollies, 1 sword tails, 2 striped raphael catfish, and of course the 2 rubbernose plecos I recently added. The filter is an Aquatech 40g filter and the temp is 76
I have done a big water change and tested the water. Here's what the water condition is right now:
pH 7.4-7.8
alkalinity: 80
total hardness: 75
nitrite: 0
nitrate: 40
The water is clear and does not smell, aside from the algae stuck to the glass.
What should I do? I don't know if this happened because of the algae bloom or because I added the 2 new fish. If this isn't ich what could it be?

Ill pick up a kit that tests for ammonia tomorrow. Im trying to upload this close-up of my catfish. After getting a really good look at him, there really aren't clear white spots. His color used to be jet black, but he looks dull and speckled grey. Im not sure if its ich or not.
The ammonia test said 0.25 ppm. Im really bummed out, those catfish were our favorite. The other fish look more active since the water change/gravel vac tho. So I guess ill treat the tank for ich?
