filter rod is harmful to fish?

Hi.. I have 10 gallon tank with 4 fishes in it. 2 panda platy and 2 zebra danios. I bought it 3 days back. While buying fishes i had asked PETCO to check the water and everything was fine so I bought 4 fishes. Till today morning everything was fine, suddenly in the afternoon I noticed my one zebra danio was stuck in filter rod (rod from where filter takes the water). So I stopped the filter and noticed that my danio is dead .
I want to know does it usually happen? or does it happen with danios in particular? if thats the case then i can change my filter or return the other danio as i dont want it to die.. What can i do to avoid it? Will this affect my other platy's too?
Please help me. I have bought fishes for the ifrst time.

I doubt that the filter killed the danio. They are fast, strong fish, that enjoy good filtration.
I'm guessing something else happened to him and he died, the filter just sucked him up afterwards.

taking a break from fish-keeping.
3 lovely male betta still keep me company.

I had noticed that his bottom part of the body had turn reddish and his fins and tail had some white spot was it due to ich?
I have one more question.. do i need to keep the filtration on for 24 hours? because right now i have switched it off.

Yes you definately need to keep the filter running at all times unless you're cleaning it. As for the fish, does it look like it's sprinkled with salt grains?

I also agree that the fish died and was sucked up afterward. A health fish should have no problem swimming past the intake.

Animal testing is a terrible idea; they get all nervous and give the wrong answers.

You will need to research about the aquarium cycle, that is probably the cause of the Danio's death. Basically, your new tank have none of the bacteria necessary to convert ammonia (produced by the fish and other waste) to nitrite (both very bad for fish, it burns their gills) to the not-so-toxic nitrate. It will take 4-6 weeks to have enough beneficial bacteria. In the meantime, there is a few things you want to do.

1. Go buy an API master test kit, or other liquid test kit for ammonia, nitrite and nitrate. Without this you are blind and won't be able to do much. It's one of the most important piece of kit, and one of the most overlooked.

Whe you have te test values, post them back, we will help you. Since I am guessing you probable want to deal with this right away, you have a few solutions to control ammonia and nitrites. First, you will need to do water changes (50% of tank volume) every other day, or when you see more than 1ppm ammonia or 0,3ppm nitrite. Use a water conditionner that will detoxify ammonia and nitrite, Prime is a good one.

Add fast growing aquarium plants, mostly stem plants or floating plants. Anacharis, Wisteria, Hygrophila, Water Sprite, Brazilian Pennywort. They will use the ammonia to feed themselves.

You said you saw white spots on the Danio. Look on the other fish, do they have white spot too ? If so, report back, we will evaluate the situation. Right now, avoir buying or using any medecine, they are toxic to fish and bacteria.

The water changes should be done every day regardless of these figures. That level of ammonia will seriously harm the fish, in fact any ammonia is already doing damage to the fish.

Here is the link to A Beginner's Guide to the Freshwater Aquarium Cycle.

Treating ich is going to be stressful to an already stressful situation. Raise the temperature slowly to 84F.

Aquarium salt is one of the best ways to cure ich without adding chemicals. You will need to acquire the salt before we proceed as to what to do with it. Go ahead though and raise the temperature SLOWLY to 84F though.

We are here to help and try and do all we can to save the fish from here on in.

10g Fry / Hospital / QT tank (as needed)

75g Saltwater Reef, Ocellaris Clownfish, Lyretail Antias (baby), Lemon damsel, Longtail Fairy Wrasse, purple dottyback, snails, crabs and a few LPS corals.

220g Still sitting empty (come on Lottery I need the numbers to come up!)

What is your water temperature now ? Do you have a heater ?

It's not very dangerous in the short term, but you will need to treat it. Ich is a parasite... Most often the not shows up when water parameters changed too fast and fish is stressed

I will get the kit tomorrow but till then i can change 50% of the water and add conditioner to the tank. Is that ok? will it help?
3 days back when I had checked the water at PETCO they said all the content is fine. So,do Ammonia and Nitrite level change in 2 days?

Yes I have a heater and the temperature right now is 80F. I will slowly increase the temperature to 84F but my other fishes wont get affected due to high temperature and salt?
