I need some advice
I am a new fish owner, I have a 190l tank (second hand) with 4 platys, 4 Danios and 4 tetras in. To help keep the tank clean I also have 3 amano shrimp. Anyway, I have a few questions that Google just doesn't help me with.
One of my tetras (Ringo) has been having problems swimming. His body keeps floating upwards as he desperatly tries to swim down, he is only pushed down by the slight current caused by the filter. I've had him for just over a week. He is still eating and no other fish are having this problem... what is happening? Is there anything to help prevent this??
I have noticed that 2 of my Danios (one is golden the other zerbra) are not really eating. They consume the food and then almost immediately regurgitate it out and swim away, all the other fish have no problem eating it (and all the Danios came from the same tank in the pet store) is there a reason why they are doing this? Is this normal behaviour?
I am still very confused by both of these occurrings, I'm hoping that you guys be able to help me. I do not want my fish to die after having them for less than a month. I will give you any information if you require it. (I take tests weekly, my Ph levels are fine and ammonia/nitrite is 0, and nitrate Is like 0.1. Thank you
