Hi everyone.

I have 4 zebras around about at 4cm in a 2ft tank. Im running a under gravel filter, eheim internal filter 2010 (220-500l/h) and eheim air pump 400 (50-400l/h).

I'm not sure if the current/flow of the water in the tank is too excessive for the fish, although i switch the internal filter off at night during feeding time and start it up in the morning again.

Hopefully someone more experienced could guide me in the right direction.

Thank you

I would suggest more hidding place. The second rock from the left looks like it can fall at any time.

Cheers.

Yes i thought about putting more hiding places, but the reason why i haven't done so is because when its time for feeding i know where they all are and i drop all there feed right about where they hide. Once they get bigger then i will definitely put more hiding places.

thanks for advice though

cheers

Hi Reg

I use sand & bb for fry in my tanks, you will find some food will get trapped between the gravel.

Turning off your internal filter is not a good idea, as the bateria in the filter can not live long without the oxygen flow so die & can pollute your water.

Luckly you are still running undergravel so you will still have some bateria alive to cycle your tank.

Turning off power heads is ok, but not filters

Thank you for the good advice Stevie
