Unusual angel behavior?

[jwal90]

Hi everyone, registered here as I purchased a 90-litre tank second hand the other day and have a question I thought you may be able to help with.

Bought the tank, including fish on Wednesday, got it back to my flat and all set up, ran it for a couple days then went and purchased more fish on Friday. One of the fish I bought was an angel fish and he seems to be acting strangely.

When I turn the lights on, he disappears in a corner and doesn't emerge again until I turn them off. He won't feed or do anything until it's dark in the tank. Is this usual behavior for an angel?


Thanks

I noticed you set this tank up on Wednesday and there are fish in the tank already. That would lead me to believe that this tank is not cycled. Is that correct? Are you testing for ammonia, nitrites? Have you read the stickies on cycling?

welcome to the forum,

we'll need to know a bit of information to help.

90L=24gallon tank, for all non metric people :P

have you cycled the tank? or just added water, then added fish?
what is your filtration?
and what are the other inhabitants in the tank, the other fish.

What are the dimensions of this tank, I balk at the idea of a mature angel [Which I am pretty sure that this isn't yet .. But one day will be] in such a small tank.

DO read the cycling with fish sticky, It's relevant. Can you list all your stock in this tank please?

Have you ever kept an aquarium before? If this is your first one you have a few things that you will need to know.

Welcome. You need to start making immediate water changes to save your fish. Unless you had an established filter with media seeded with beneficial bacteria, you have set up a tank without properly cycling it and will need to do diligent water changes to save your fish.
please go to the beginners section and read the stickie on cycling with fish. It will tell you what you need to track your tank's water perimeters and what you need to do to keep the fish alive. As soon as you do that, come back to us with questions and we will attempt to help.

I should clarify I bought the tank second hand, so it was already established when I brought it home. Apologies, I probably given you guys a bit more info there.

When I bought the tank it came with the fish, rocks, plants etc. The fish were 4x neon tetra, 4x harlequins, 4x glow-light tetras and a chinese algae eater. I had to add some extra water to the tank to top it up but I treated it first. After I'd done all that and the fish looked happy I bought 4 more black phantoms, a shrimp and the angel fish.

I wouldn't say there's an issue with the size, I picked out the smallest angel fish I could find and he's only around 3 times bigger than the tetra.

I did changed one of the filter pads but it doesn't seem to have caused any issues. I also added some 'general tonic' which came with the tank when I bought it because it was supposed to help with diseases etc.

Hope I've given you enough info there, let me know if you need to know anything else.


Thanks
