Hi all, After a few years I decided to convert my 30 gallon gourami tank into a livebearer community tank. I re-homed the last surviving gourami and added 4 platys, 9 guppies and 8 tetra. Stupidly I didn’t quarantine in any way and now regretting it (I’m not an experienced fish keeper I’ve only...

“Santa” (my mother)got my 5 year old fish for Christmas. I have 2 rescued dogs and a cat but I’ve never had fish. We now have a 20 gallon community tank. There is a female betta (who is the one I am most worried about), cory cats, glow tetras (who the people at the store said would be perfect...

Title is an attention grabber, I know, but I am back again after having minimal issues with Grosso! (insert massive sigh here) I got sick of the 10 gallon shortly after experiencing back to back canister issues and it almost killing him, so shortly after I upgraded to a 36G and things have been...

I already cleaned out my filter with tap water, but afterwards was told not to do that because it rids beneficial bacteria. But there's other items in the tank that can have good bacteria too right? Like the decor, plants, and gravel hasn't been messed with. What effect will this have on my...

I just completely redid my 40 gal tank after most of my fish died from ich. I took water from that tank and put it into my old 10 gal for now, but it started to turn slightly green. My stepdad who keeps fish said I should put that water back in because it had beneficial bacteria that the fish...

Hi, I know it’s a blurry picture but can anyone identify what is happening in my goldfish tank? I am at a total loss. It’s a 70 gallon. Here is the back story. I have had this specific goldfish tank for over 2 years, have been keeping fish my whole life, and have many other tanks in my house...

Hi we have just had our whole tank wiped out in a couple of days. First signs of stress were on Friday evening when they didn't eat. Then we treated with wide spectrum treatment but over the weekend they have all turned belly up! From what I can see it was columnaris bacterial infection as the...

Hi, I would like to know if It's better to remove my filter on my 10g at this point. It's an interal filter but I stopped it about a month ago because of the sound. I only have 8 ember tetras and 2 small shrimps with a bunch of plants. The thing is I don't know if the bacteria are still alive...

Hello everyone! You can skip the first few paragraphs of my fish history since its too long but I need help with my fishless cycling!! I have a 10G tank that originally started with 5 mollies. After two months, three of them got sick and died one after another. The reasonthat I can think of...

I've been cycling my tank for a few days (with flakes and Fritz Zyme 7), and I was wondering if anyone else has had this white film? I haven't tested the parameters yet (I'm planning to on Monday), but I just need to know if this is something harmful or just a natural part of the cycle? It...

I'm planning on setting up a 21 litre (5 gallon) nano early next year - I will be using RO water and remineralising. One question I have is, where does the friendly bacteria come from? Does it need to be added or is it naturally found? (I assume if using RO water, there's unlikely to be a...

So - here's my plan for my Nano Tank filter set up. My Nano Tank comes with built in compartments in the back for the filter, water pump and heater. Originally it came with a large black sponge in the middle compartment (areas 4-5 in the drawing) - which I assumed was the Carbon filter but the...

Hello, I am new to the aquatic world of fish, and I have recently purchased a very sick betta that I am trying my best to help. When i first purchased him(nearly two months ago), he was In poor health and bad living conditions. He had no color in his body or fins from what I’m assuming was...

Hi everyone I’m cycling an old tank it’s about the 3rd day I’ve added fish flakes and now I have these white particles on the top of the tank. Some are collecting on surfaces but mostly on the top of the tank. Does anyone know what this is and or if it is normal?

Hey I just put the rest of the bottle of Tetra SafeStart I got a few days ago in my tank, the bottled bacteria I had before might've been dead and I heard good things about this brand. Anyways the main difference between this bacteria and the other brands I've used is that when I put it in, it...

Hi everyone, does anyone know what this white stuff is in my tank? These are old pictures from a year ago. I’ve since taken my tanks down because of this white stuff, I’ve bleached everything and this stuff just seems to keep coming back. I’ve set up this tank again with just water and afilter...

Good evening all! I have a long fin danio that I noticed today has his back fins separated into three parts, all my other leopard danios don’t have fins like this so I got concerned and separated them from the others in my quarantine/hospital tank. I checked my water parameters and my ammonia...

Pictured below is my male betta in the store (20 December 19) followed by his first days in his new home. He instantly became much more vibrant which I was very happy about. However he then developed a dark spot by his lip - starting off as a small grey dot. He was also glass surfing for...

I have lost the cycling on at least 2 of my 4 tanks - perhaps all of them. The biggest issue is that ammonia/ammonium will NOT convert to nitrites to any great extent. So my readings of high total ammonia just stay high I add Prime every other day to make sure that there is no Active ammonia...

Could it be a bacteria bloom / algae bloom? How can I tell the difference? This is in a 10 gallon tank. Not sure if this is a result of a water change (I do 15% every week) and a few weeks ago I had to replace the filter cartridge. Is that the reason why there is a bloom in the first place...

Hi there This is my first time posting here so apologies if I make any faux-pas. My boyfriend recently got a male and female dwarf Gourami. Originally they were both very lively and seemed happy, but the male has been acting off recently. He often hides in the back, and is generally quite...

I dirted and reworked my tank about 3 weeks ago, and I've got some heavy clouded water on my hands. It's been there for over 2 weeks now, and I'm unsure what to do. I've done a lot of water changes, but it's not helping. I also have a UV filter, but the bulb seems to be out. Ammonia and nitrite...

Hello everyone, So, I've got a fairly new set up going in a 20 G long, planted tank with out door natural wood and land scape as some of the scape for my tank. This (in the photo) is growing on a piece of wood submerged in the tank. Its been there for about a week but over night got a lot...

I'm doing a fishless cycle of a dirted tank. The filter is cycled and has been going for over a year. Since I set up the tank more of this slimy tendrily stuff has appeared. On closer inspection under the microscope it turned out to be bacteria and infusoria. Anyone knows about this?

I have in my tall 20 gallon tank what I believe to be as cyanobacteria. It's a green, slime-like film covering the gravel on the bottom of my tank. It appeared days after I put in a marimo moss ball. I have some questions regarding the outbreak. - Is it imperative I clean the cyanobacteria...

Hello all, I have a beautiful young Green Severum cichlid in a 200l community tank. He's usually very active and friendly, but recently he's been hiding under some Anubias leaves towards the back of my tank, and I've noticed he has small, whitish indents all around his head. These seem to be...

Can anyone help my fish please? I thought the gourami had damaged it's side crashing into a branch in the tank. As the side wasn't healing and looked white in the damaged area I moved the gourami to a QT and started treating with Melafix. What's weird is the white is not cotton like but looks...

I think I have been feeding a little too much and now I have some fuzzy gray/white stuff growing in my tank. I read in a few places that it could be a bacterial fungus. It only started growing in the last day - day and a half. My fish managed to fool me into thinking they would eat more than I...

I really need someone to respond to this post asap!   I had an issue a month ago where i had foamy bubbles forming on the surface of the water, and all my fish seemed to be struggling to breathe. Now the bubbles are back in a much more mild form, yet my fish are all breathing ridiculously hard...
