    Direction

    Acclimating Your Betta Fish

    1. Temperature Match: Ensure the new tank's water temperature matches the water the Betta fish was previously in.
    2. Float the Bag: Float the bag with the Betta fish in the new tank for 15-20 minutes to adjust to the temperature.
    3. Gradual Water Mixing: Add small amounts of tank water into the bag every 5-10 minutes to help the fish adjust to new water parameters.
    4. Net Transfer: Gently transfer the Betta fish from the bag into the tank using a net.
    5. Dim Lighting: Keep tank lights off initially to reduce stress on the fish.
    6. Monitor Behavior: Watch for signs of stress and discomfort, adjusting as needed.
    7. Regular Observation: Check on the Betta fish frequently in the first days to ensure it's adjusting well.
    8. Water Testing: Regularly test water parameters to ensure they're suitable for Betta fish.
    9. Provide Hiding Places: Offer hiding spots to make the Betta feel secure.
    10. Avoid Overfeeding: Feed sparingly to maintain water quality.
    11. Patience: Give the Betta time to acclimate, which may take a few days.

    🖤 Black Hulk Halfmoon Male Betta | You Pick Fish

    Unleash the darkness. Meet the Black Hulk Halfmoon Male Betta — a powerful, shadow-dominant specimen inspired by the unstoppable force of the Hulk. 💪🖤

    This betta features a deep solid black body paired with piercing green “Hulk eyes” that glow with intensity under light. The contrast is bold, aggressive, and impossible to ignore — like a monster lurking in the shadows.

    Each fish is individually photographed and filmed, so you pick the exact Hulk you receive. No randomness. No guesswork. What you see is exactly what arrives.

    🧬 Black Hulk Betta Bio

    The Black Hulk line is bred for one purpose — pure dominance in visual form. Achieving a clean, solid black body with strong pigmentation and minimal color break is already rare… but pairing it with vivid green eye expression takes it to another level.

    This line showcases:

    • 🖤 Ultra deep solid black body
    • 💚 Signature Hulk-inspired green eyes
    • 🖤 Clean color saturation with minimal pattern break
    • 💪 Strong halfmoon finnage with wide tail spread

    The Halfmoon tail opens up to a full 180° spread, giving this betta a bold, commanding presence in any tank. When flaring, it looks like a dark force expanding — calm… until it’s not.

    Under the right lighting, the black absorbs everything around it, while the green eyes cut through like pure energy. ⚡

    This is not your average betta. This is a collector-grade monster. 🏆

    Adore my lil helldiver Reaper so much! Looks exactly like the picture! He is so curious and always wants to see what we are up to, loves to follow you around the room in his tank! Can’t wait to get another! The colors are absolutely insane in person, absolutely obsessed!

    I am so happy with my new Betta. He arrived happy and healthy and strong. He’s spent his time exploring the plants and crevices and he’s already waiting at the top when the lights come on in the morning to be fed by hand. He truly loves a treat every now and then of blood worms. He comes right up to my hand when I perform maintenance on the tank and comes to the glass when he sees me approach the tank.

    Cannot recommend Tropic Flow enough! Made my son’s birthday super special with their Hulk Betta! Even revised my order when the fish I first picked wasn’t going to arrive in time. They truly care! About their fish & customer experience. Our betta is beautiful & so social. Healthy too, packed so carefully. We are so happy with our purchase! The snails were risky on my part (East Coast). Yellow spotted may not have been my best choice (1 alive) but they loaded us with extras anyhow and the plant package for Betta, STUNNING. Wouldn’t change a thing thank you guys endlessly!!! Forever customer!

    From the very start of picking out my beautiful half moon betta on line to being informed of every step of its traveling times before arriving through the mail to my home was a very stress free experience. He was packed so well and safe. He looked so healthy and happy. I would definitely recommend this company to all. Very Professional!! A+ I provided this cute little guy two aquariums on the smaller side with a connecting water tube bridge. As soon as he figured out how to cross over, he seems to love it! It's also fun for me to watch him cross. I have had him now for a month as he seems to be very happy and healthy in his new home.

    I got the wrong fish. I order a really beautiful betta but got a completely different one with different colors. Although, their reapond time takes a while and is annoying, they did refuld me the full amount of the beautiful betta that i had my heart set on(sad) i do have the boy they sent me by mistake, hes just not as pretty. His name is Bruce and hes growing on me. Still very sad about the betta i really, really wanted though.

    Fish arrived dead, no resolution. Been over a week and they have done absolutely nothing. Never again.
