I have a 75 gal. Aquarium that I have been running for about 8 months. I had five fish doing pretty well I decided to get a red flame angel and a lemon peel angel. They died after 2 weeks. I then got a goby and 2. CLeaner shrimp the next day my 2 clown fish died. Any ideas on what is happening. I like this hobby but I’m starting to get a little discouraged. Please any info will be appreciated
