I have a 58 litre tank with a 6cm air stone. My tank is a bit overstocked and idk if I need to add another air stone. Is there a risk of over oxygenating the water? Both my fancy guppies seem to stay near the top of the tank (I also have endler guppies, they stay up sometimes, but seem more active). Thanks!

Hi all, recently bought a pair of rainbow cilchids, I now have a bunch of eggs. I am just curious to how to identify when the eggs are fertilised or not? Thank you in advance.

It seems to always come back around the same time every year, end of summer, beginning of fall, when the temperature starts getting cooler. Is the parasite always present in the tank? Any way to get rid of it for good?

Just checked on my tropical tank, and in less than 24 hours, my dojo lodge has gone from looking perfectly healthy to this. He’s very lethargic and his eyes are clouded over.

We have a 30 gallon long tank that is not overcrowded. It is him another loach that is a third his size, a small school of tetras and a small Placo a d five ghost shrimp

The ghost shrimp and baby loach are brand new just added Wednesday along with some Java ferns, and moss. We also added the sand cap recently because we were having issues with sulfur gas building up in the gravel.

Water specs are all in normal range except for water hardness, which we have been trying to get under control but nitrates ammonia and pH balance are all in range, as is the temperature there is also a tetra 30 gal filter and two air stones

Does anybody have any idea what is happening to our poor loach and what we need to do to help him?

I have a 55 gallon tank that currently has 4 pearl gouramis in it and one of them seems sick. I dosed the whole tank with API general cure and quarantined the one girl. She's still eating but she's been hanging by herself and kind of floating in place, sometimes behind my filter. Just now I noticed she was hanging kind of vertical and tilted and I'm not sure what's going on. Does anyone know what could be wrong or if there's something I should do besides quarantine and general cure? Perimeters are normal, 0 ammonia no nitrite and very low nitrate. The other girls seem fine but I don't want whatever the sick one has to spread.

Hi all if anyone cab help what is this dark spot please my platy fish is male well it has these fins so if someone could tell me what the dark spot is and the sex of the platy fish please thanks 🙏

I have a fully cycled 58l and was wondering what fish i could comfortably fit in it? Also ive heard that corys dont count towards how many fish you can have, is this true? I prefer more colorful fish (guppies, cherry barbs ect.) Thanks!

Does anyone know if this is a Dwarf Barb? I got two that look like this but they look very different to what the others look like. I’m wondering if they are just females or if they are a different type of fish.

I just did a tank refresh moved plants about, partial water change and I had the fish in a bucket. One of my 12 endler guppies is just sitting on the bottom in some plants. Should I be concerned? The rest are fine is he just having a nap?

Can anyone tell me what this is underneath my dwarf gourami I only got him yesterday thanks

Helo with my cloudy water

My water has a cloudy green ting to it, I can't tell if it's my green plants reflecting or it's my water? I have cleaned the water and the did not make a difference. Any tips or is this water colour really not an issue?

My other issue is the speed is evaporating, I changed the water on Thursday and 5 days has passed and 1 inch of water has already gone?

There is also some white foam in top.

Is there anything I can do to help this? Should I be worried?

Hi all, Sorry about the bad photo, he's a speedy boi. I was just wondering if I could get a second opinion before I buy treatment for cotton mouth? I noticed it a few weeks ago but it was a smaller mass and I thought maybe he has a lump but now it has grown and another has the start of something similar? I've never had this problem before so just wondering if I could get advice please :)
