Should I Get More Fish Now?

[Fishmanperson]

Hello, recently all my fish died expect for my angelfish because I added to much algae fix by accident. My angelfish seem to be acting normal but they have little blue spots on their eyes that they didn't have before. My ph is also still a little higher than usual at 8.2. Should I wait a little longer and do a big water change or do you guys think it's okay now? I have done multiple big water changes now.

I would say add some driftwood to bring that pH gradually down and do another big WC (75% if possible). Test your water and if there's no Ammonia, no Nitrite, and manageable Nitrates, wait a day or so to help parameters level out and then you're good to go.

A bit more info please.

1. How long has the aquarium been set up and running? Is it cycled? What are the readings?

2. What were the fish that died?

3. How large is the aquarium?

4. Are the angles young or mature? How many do you have?

5. Did this happened after non-quarantined fish were added?

6. What filtration is being used?

7. What where you feeding them, and did you change the type of food right before this happened?

8. Any aerosol sprays used near by?

I ask all these questions because while algae killer does lower the O2 of the water there may be an underlying issue.

It strikes me as strange that the angels are the only ones to survive.

My aquarium has been up and running for about a year now and it is cycled. The ammonia is 0 the nitrite is 0 and the nitrate is 0 usually it's 10. The fish that died were bleeding heart tetra, neon tetra, and clown pleco. The aquarium is 55 gallons large. The angelfish are almost mature and there are 3 of them. This did happen after the non-quarantined fish were added. I am using biological filtration. I was feeding them flakes and shrimp every once in a while and I did not change the type of food. Their is no aerosal sprays that I know of near by.

Do you notice if the angels are courting? If they are pairing off that might be cause for aggression.

No I don't think they are courting.
