ood day. I Am new to bettas. im from philippines.. ^^
i have a 2.5gal. tank, and 1 male crown tail betta,.
and i want to add a 2 mollie fish, it is possible they leave together? or they are going to fight? and what kind of fresh fish can leave with male betta? please any one answer this.. thank you
Please don't add any more fish to a 2.5 gallon tank. That small volume of water is only enough for your betta, no tank mates!!! You will have an extremely heavy build up of ammonia in your tank, it will kill your fish. Do you have a filter? Is your tank cycled? If it's just recently set up even with a filter, you have to do plenty of water changes with just your betta alone.
I wouldn't even put a snail in a tank that small. I also have four 2.5 gallons, and there just isn't enough space. Snails produce a lot of waste, and even though they may eat leftover food, fish poopies, etc, it's not worth it to have one in a tank that small. As for the ghost shrimp... I wouldn't recommend it. It *might* work, but more likely than not your betta would eat it. Definitely no mollies, though.
welcome to the forum! (: I'd like to say that a 2.5 gallon is the smallest tank that someone should get for a single betta. like everyone else is advising, mollies, or any other fish for that matter, wouldn't be a good tankmate for your betta. just keep it simple for your betta, it definately doesn't mind having the tank to itself.
