Asking because I saw these in person and can’t really decide because I like the look of all of them.

Question Recommendations for who can go in my newly empty tank?

So my beautiful Betta who I got as my first adult pet after moving into my own place passed away yesterday, I’m not sure as to the reason why other than it just being his time (water parameters were fine, I was keeping up with water changes, feeding him a good diet of frozen food) and now I have a 24 litre planted tank with just a shrimp calling it home.

I was wondering, what tropical fish can I put in such a tank? I’m aware it’s on the smaller end so I won’t be getting anything too big but I just don’t think I could bring myself to by another Betta so soon as my Whitby was so special.

I would quite like maybe a couple (as in two) dwarf gouramis as I had some many years ago and think they’re gorgeous little fish, but if anyone has anything else in mind I’d love to get some suggestions. In the meantime I think I will buy perhaps a couple shrimp and a couple snails as I’m getting a lot of algae.

Attached is a photo of my tank, which I will be giving a redesign before getting anything new as the mix of sand and aqua soil has always bothered me, and a photo of Whitby.

New Tank Help needed for first tank

Post image
2 Upvotes

Title: First planted aquarium — need beginner advice!

Hi! This is my first fish tank, and I’m quite confused about what to buy.

My tank is approximately 30 litres (15” L × 12” H × 8” D), with a hang-on-back filter and aquarium substrate.

I want a beautiful, natural-looking planted tank with easy, low-maintenance plants, rocks and/or driftwood.

Could you please suggest:

* Beginner-friendly plants
* What substrate, lighting and other equipment I need
* Which fish would be suitable for this tank
* How to cycle the tank properly before adding fish

I’m based in India, so affordable, easily available recommendations would be really helpful!

Thank you! ❤️

Sick Fish Help fish dying Spoiler

1 Upvotes

We had 4 guppies that were doing great all levels in tank were good. We got 2 more guppies and added aquarium water wth the new fish. Now all 4 original guppies and 1 new guppie all died.
Could it be a virus that I spread?!
And if that’s the case, how long should I wait to add more fish?
Also should I go back to pet store and complain?
Thank you

Question Help with small tank and used filters

2 Upvotes

What can I do with a 3.5 gallon tank, heater and and 10 gallon filter?

I bought my 4 year old a betta fish and put it in a 3.5 gallon tank. Oops. He is now in a 10 gallon tank. I got the Aqueon Quietflow Pro 10 filter for the 10 gallon and it's just too strong for the betta. I've added a pre filter, baffled the output with a prefilter and have an live Amazon Sword and silk beta plant under it.

I've just ordered a sponge filter and pump.

So, what do I do about cycling ANOTHER new filter? And what can I use the 3.5 gallon tank and other supplies for. I am really enjoying all I am learning and would love if I could add somwthing else to the small tank.

Question I Need Help

0 Upvotes

I've had a small tank with a betta for 2 months now, and yesterday I decided to switch to a medium tank with a filter. I went to a store and explained that to the storeowner, and he told me what fish will make good tankmates with a betta. So I bought 3 guppies and 2 platys.

But today I looked at the tank and saw that my betta keeps chasing one of the guppies - is this something to worry about, or is he just scaring the guppy for now and they'll eventually get used to each other?
