I introduced a healthy Arowana into it's new (already cycled) tank and it swam around rapidly and then went to the bottom of the tank and died. We introduced it to the water when it was still in the bag. RIP. My other fish that was also in there also died the next day. RIP x2. There are still...

Is it possible to keep an oscar in either a 75g or 90g

Hi ! i'm new here, i stumbled across this website as I was looking for a solution or an explanation to an "issue" with my both male and female scarlet crayfish . I bought them roughly a week ago, i'm not an expert but, they seemed ok, and I added ladder for them to climb up to the surface. only...

Alright, sooo... I posted about adding an Oscar to my tank with Tiger Barbs and Crays, but have decided against it... However, I now took out the more aggressive, two-pincered Cray and put it into my father's large tank after one of the barbs had lost a fin on one side and couldn't swim, only...

I have had an awful algae problem in my 20 gallon long since I started it 2 months ago. I started a fluval 2.0 on the tank. In the beginning, I had the light on for 10 hours. Algae ran rampid and coated every surface. String algae was everywhere. I then changed the light to 8 hours. The string...

A continuation of my previous thread “Fantasy Fish Battle”. I’ve accumulated who my top dogs would be so I’m letting you guys pick the champ! If choice isn’t listed, post who you’d pick. Explainations of your pick would be appreciated, thanks guys! (No snakeheads as they are illegal in America)

I have two bass that are around 7" now and all there eatting is blood worms still and here and there if I mix beef heart or fish eggs with the worms they will accidentally eat them. But I really would like to get them two eat krill so i can but them in my 240g with a 16" arowana. And two...

Hey guys, I’ve noticed my little 3” common wolf is not in his usual cave and is hovering at the waterline and occssionnly darts to the other side of the tank. Before he was doing this, I noticed a cut/abrasion on his side. All other fish in the tank are completely fine. Any and all help needed!!!

I have been researching for my Lake Malawi Mbuna Cichlid tank and what to stock it with. I have four so far that I am pretty sure will work and I know we want. I was going to take the lazy way out and get a bunch of those four, but then I went to my LFS and saw the beauty in the variety they had...

I was wondering if these fish could go together in a 75 gallon planted community. - Rainbowfish -congo tetras - angelfish -Denison barbs I feel like it could have its issues when it comes to feeding time due to how slow angels are. Suggestions?

So i was on aq advisor, I was just getting a plain bare bones look at a stocking Idea, went i added 4 bolivion rams, it said Warning: Your selected species may eventually require 128% of your aquarium space. You may need to deal with territorial aggressions later on. weirded out by this I...

Hi guys I've had this bluegill for about 2 weeks and he was eating the first week perfectly. All of a sudden he stopped eating the meal worms I was feeding or any other food I tried. He went from coming to the top of the tank when I came in the room to not moving at all. The tank is cycled and...

my 3” blue Flowerhorn got attacked by my Oscar in a 125g tank. I think he got scratched on a rock in the tank because he has pretty deep cuts down his side. I separated my Oscar and put him in a 75g by himself, but the Flowerhorn kept getting worse. The scratches turned red and he started...

I bought this catfish at my local Lfs and they sold it as a pimelodela cat but I’ve searched it up and my fish looks nothing like one. He’s a light grey and he’s about 2.5 inches, (I attached pictures of the fish)

So i picked this green severum up at a lfs for 20 bucks he's looking ROUGH! They told me a couple from Columbus dropped him off for store credit, so the excuse of why he so rough looking is because of the 2-hour Drive in a bucket, and I beleave the poor water quality of course at its original...

Hi there! I’ve recently set up a tropical aquarium (a month ago) and have been slowly adding fish with advice from my LFS. I’ve been keeping a close eye on them and have (perhaps unwisely) carefully chosen names for all 13 of them. Today I came home from work and as usual checked the...

I know that this is a commonly asked question but I have a ph of 7.6 and am not so sure about tetras (which I really want to add). I tried both wild and tank raised cardinal tetras in my 20 gal long, full cycled, no ammonia or nitrite, and around 20 nitrate. They all died within a week both...

Not mine but my friend. Can fire eel morph their colour late stage? I know certain catfish can morph from normal to leucistic or xanthic. But this eel morph from normal to xanthic and back to normal. Can anyone explain why???

Hey all, I have a 5 inch Senegal Bichir that has a nostril that looks like it is decaying compared to the other one. Any idea what’s wrong? He jumped into the filtration compartment in the back a while ago and I’m not sure if he injured it then or not.

Hi all, I am close to ordering my first truly big aquarium. It is meant to be underneath the windows of the front of my house so there is no option of putting the tank on a stand. I came up with sort of a "side-sump" design and i would like to have feedback on it. The dimensions are...
