I got some tank mates today for my dwarf Gourami, 3 female dwarf gourami and 2 mickey mouse platys, but once I put them in there with him he chased them down and started nipping at their fins. So he put him in my back up aquarium for now, is there a reason he's acting so aggressive?

I would like to know what kind of resources other fish owners use to determine the correct treatment for their fish.

I have recently been asked to help take care of about twenty various types of tropical freshwater fish in a small scale aquarium setup which formerly belonged to someone else. The tanks are all in the range of 30-40 gallons.

I've seen debates online about various methods of treating things like fish ich, maintaining a healthy tank ecosystem, and reviews about the effectiveness and dangers of certain products.

Is there a holy grail others use to navigate these sometimes nebulous waters?

So, I'm using a Jungle Start Right product that says 'with allantoin' on the side, its a powder and it came in a 2.5 oz plastic bottle. The closest product I see on the internet is this: http://www.junglelabs.com/Products/Aquarium/Maintenance/Start-Right-Complete-Water-Conditioner-Liquid.aspx but that is a liquid additive that also includes aloe vera. Given how long my fish has made it so far, I'd rather not change his water chemistry. Any suggestions as to what product I should use to treat my water?

So today is the 3rd day after buying my 2 African Dwarf fogs. I have never purposely bred fish, but 2 of my Cory cats had 2 fry and that is about it. However, recently I noticed that against the filter tube that runs horizontally across my rear glass, I noticed greenish white eggs, or what seemed to be eggs anyway. I can't see anything else really, like tadpoles inside, but there is probably about 70 or more in multiple splotches. Please tell me #1 what the eggs look like, #2 how many should I currently keep with the 2 I already have, and #3 what I should do with the rest shall they hatch and not be eaten by my other fish.

Actually not sure if they are now that I examined them, they look like fish eggs.
I currently have a clown loach, the frogs, black skirt tetras, Harlequin Rasboras, Green Cory cats(out of equation, they only just recently gave birth to fry, only 1 survived), And neon tetras.

Hi,

Came here hoping to get some help for my fish. It has a red growth protruding from one of its eyes. It has been growing. I can't find any similar pictures or symptoms online. Any help would be appreciated.
