Set the aperture to the widest setting (lowest number, eg f2.8 lets in more light than f4.0). Put as much light on the tank as you can. A regular fluorescent lamp is not going to be nearly bright enough. Let the camera decide the shutter speed - if it is any longer than about 1/50 sec you...

What's the prize for POTY?

Neither of those are particularly common, especially seiboldi, so I doubt you will find anybody who can suggest anything other than to try it but be watchful of them.

Everything looks great except the fake plants. They look to artificial and I think they detract from the overall appearance of the tank.

Hi, The function of "biomedia" is to provide adequate space for bacteria to proliferate. These bacteria convert the ammonia (very toxic) produced by fish into nitrite (also toxic) and then nitrate (relatively nontoxic). They will live on any surface of the tank, be it driftwood or gravel or...

I'm pretty sure the center brace is structural on a standard 75 gallon tank; remove at your own risk. You can put one filter on the end but you will need to modify the lids.

I doubt you need that much flow even on such a large tank. That style of pump (propeller rather than impeller) spreads out the jet a lot more but it is still a huge amount of water. Are you trying to create river-like conditions for the inhabitants or just keep the water cleaner? If the latter...

Those are amazon sword plants in case you don't know. They aren't very demanding plants but if you only have the stock lighting on the tank (eg a single or double fluorescent light strip) they may suffer.

Another plant to consider is Rotala. I have found that it grows quite well in moderate lighting levels, but as with most plants it really explodes in a brightly lit tank with pressurized CO2. A CO2 system comprises a tank (generally 5 lb, aluminum or steel) a regulator, which reduces the output...

What plants are you trying to grow? Beginner plants such as java fern are very hardy and should grow easily in the tank conditions you describe. It's possible your plants aren't actually aquatic; chain pet stores tend to sell plants as aquatic when in fact they are semi-aquatic (leaves need to...

Midas, only if it's barred though.

A 75 gallon tank can be found for about $50 in my area used. Consider a smaller species of cichlid if you can't get a larger tank; there are many species that won't grow so large as an oscar.

Thanks pharaoh for taking the time to set this up. I'm surprised to see only 7 submissions though, quite a dropoff from last month.

Barred midas take on a really prominent barred pattern when they are breeding (hence the name)

Mine's not that big yet Too many goldfish in this thread so far though :grinno:

iodized salt is fine to use

What a wonderful thread full of unsubstantiated claims and dismissal of basic math.
