Need some help! Two fish dead in two weeks

Postby timmcg1011 » Sat Jul 06, 2019 11:37 am

Need some expertise here. I lost two Malawi cichlids in two weeks. I've had the tank established for about 4 months now. Ammonia = 0 ppm, Nitrites = 0 ppm, Nitrates around 10 ppm.

Just did a 50% water change and added Prime.

I do weekly water changes. Cleaning out the filter around once every three weeks.

pH = 8.0

Temp around 84 degrees

Feeding Tetra Cichlid Flakes, Omega one sinking pellets and hikari floating pellets.

Lost a lemon jake two weeks ago and today found one of my german red peacocks dead when doing a water change today.

No sign of bloat. No stringy feces.

I feed between twice and three times daily. One day a week I'll feed them just once.

Can anyone suggest what I should do next? I'm anxious about losing more fish.

60 gallon tank with now 13 fish in it. No aggression that I see. Thought things were going great.

Last thing...I put in some live potted plants about two weeks ago and the store owner sold me "Flourish" for the plants. Supposed to be safe. Adding 1 cap full every week.
That's the only change to the tank in the last few months.

Thanks for any help you can offer.

What are the dimensions of the 60G? Are the fish all male? What is your species list?

For a start gradually over a period of 4 days lower the temp to 78 degrees. In the meantime, increase oxygenation by increasing surface agitation.

I have power heads on one side of the tank and there's good surface agitation. I will lower the temp. over the next few days.

tank is 12.75 in L x 48.5 in W x 25 in H

Fish:

One lemon jake
one ob
one german red peacock
two male borleyi
one taiwan reef
two electric blue ahli(one male, one female I believe)
two socolofi (small)
two cats

If you are going to keep females, Malawi are better kept in large harem groups with 1m:4f. Since you seem to be going more for a variety of males, I would remove all the females.

To continue with the all-male stocking, what usually works best is one of each species and no 2 fish that look alike.

I would expect the socolofi to be too aggressive with haps and peacocks so I would remove those.
