help a noob

I’ve had my Betta about a month now and today I spotted this white/grey stuff on his tail. Is this a sign of disease? Or has he just got something stuck on there? His behaviour has not changed, he is still swimming around, eating and coming to the front of his tank to be sociable. He has a...

I bought a pair of female rainbow fish (i did not know they were schooling fish until i put them in my tank....and after that i am not able to find rainbows anywhere)....they are around 10 months with me(quite happy...no stress) recently(around a month) i am noticing one of the rainbow acting...

So I’ve got a 29 gallon tank that’s divided in half. On one side I have my male guppies and the other my female. Anyway, I have one of the male guppies in an isolation box because he kept endlessly harassing a single other male guppy. The isolation box is mesh so it just sits in the main tank...

Hi! I've had a betta fish for a few months now, and with every water change his fin recedes and has long tears along it. Initially I was told it was most likely fin rot, and I tried using bettafix and trisulfur tablets which helped a little, but would never cure his tail leaving it as bad as it...

Okay, so I’ve had a small 5 gal with glofish for years, and I upgraded to a 15 not too long ago. Maybe a month ish? I let it sit with plants and filter for a while before acclimating the 4 glo tetras I had into it (plus some snails), and about a week ago I got another tetra and 5 cory cats. I...

Hello! Can someone give me some tips at caring for 160+ guppy fry. My aunt wanted to throw her sons guppies (I separated them by gender the first time I got them) so I decided to adopt them since my brother has been wanting some for a while now, and noticed that 3 of them was pregnant, the...

So I bought this flowerhorn from ebay earlier this year. Personally I think it's a female but the eBay ad said it was male. Does Doug have poor genetics or is he a different type of FH as it also said he's supposed to be a super red dragon FH, but he has little to no red. Much appreciation in...

Anyone know what could be wrong with my poor Cambria? I’ve had her for over 3 years, bought her when she had bad fin and tail rot. Recently she’s had white specs on her body that looked like her fins were “flaking” off, I thought it was Ich, or columnaris so ive used melafix and fungus cure, but...

I know most people say the later the better but I don't really have the patience. I'm at the nitrate no3 spike right now. After the spike is over how soon can I put corals? Btw I'm using Fritz turbo start 900. Thank you.

Hi everyone! I've had this tank for close to a year now and recently this algae has popped up. I've undergone multiple water changes, but it keeps coming back. What is it and what can I do? Thank you so much!!

I have a 20 gal tank with wcmm and just decided to add guppies. The place i got them from was like a mom and pops fish store so I thought it would be okay to just add them in. Now that ive been looking more at the females I noticed some have this sting coming out of them but only them and I know...

I have these pieces of wood that were used in my spider tank and I’m wondering if it’s safe to use in my aquarium. I have a feeling the one at the front isn’t as it’s very light and feels and possibly porous. Any advice would be greatly appreciated. I know it will need to be thoroughly cleaned...

Hi all So 3 days ago I started to cycle my tank. I added 3ml of ammonia and confirmed the amount by testing the water which measure 3.0mg/l. Here I am testing again and ammonia (nh3 & nh4) are now at 0mg/l, Nitrite is at 0.3mg/l & nitrate is at 25mg/l. I’ve read through the fishless cycle...

Hi I just purchased 6 panda Corys and for the most part 5 of them seemed pretty healthy. But one of them I noticed has a thin curvy line in its tail and anal fin. I had no idea what it was so right now I put it quarantined in another tank but I was hoping someone knew what it might be? The...

Hello! I’m super new to fish keeping and did the bad newcomer thing and bought a tank that fit my space and then put whatever fish was pretty into it. The three guppies got too stressed out and died, so now I have the two male black mollies left (happy I think). I’ve read that they should be in...

I've had my betta for months now and have changed nothing in my routine, but lately he has developed white spots on his left face and top of his back (and a few other places that didn't show up well in photos, all small). I've seen posts of somewhat similar conditions being aggressively deadly...

I got a 5.5 gal tank today as an upgrade for my betta. I need to cycle it but I need to know where to start and what to do. Today I put rocks, water, the filter, and stress coat in the tank and a couple cups of water from my other tank. Is there a way to cycle without buying ammonia? Thanks for...
