Hi! Some help with my new aquarium please!

rok is right, most gobies are brackish, and even more are completely salt water.

sure they are born in freshwater, but will deffinatly need brackish water as they age

Even if it is a brackish fish, i believe you can slowly ween them to be 99% freshwater fish

They won't live as long though, in full freshwater, if they are a brackish fish. Yes you can put any fish into water that isn't suited for it and it will live for awhile, but not like it would in the appropriate water. If the fish is brackish, keep it in a brackish tank with other fish that like that water.

The planet catfish log on the Synodontis angelicus says it gets around 9.5in. Even that is too big for a 25 or 35g tank. I'd take it back and get some cories that are small enough to live in your tank. Or get like a 100g tank so you can have a group of those guys.

Hey, hey, im back.

Iv got my tank set up and started on the fishless cycle.

Running some medium grit smooth gravel

Iv toned down my fish choices a bit. Right now implanning on going with a single Banjo Cat, and a pair of Bandit Corys. a PH of 7 seems to be right in the middle of bolth their prefered ranges, and they are bolth known to be peacefull community fish.

I am using a Bio Wheel Penguin 150.

I tested my water. The PH is very high, and is around 8.5. I noticed that the alkalinity is also ver high, around 240 or 250. What should I use to get the PH and Alkalinity down to aceptable levels?

I'm not sure about how to get the pH down....but I'll comment on the cories. They are shoaling fish, so you'll need more than a pair. I suggest you get atleast 4...6 would be even better.
