@JKFish: lolol I'm serious! I first used that tank for my two goldfish when I didn't know any better. I had to clean it almost all of the time. Unfortunately they died from stunting/various issues so my two NEW goldfish were only in there for a year tops, with even more diligent cleaning. My goldfishes are now in a bigger tank, and so the 2.5 has been cleaned and sitting in the sun for 6 months until I got Shimmoo, my first betta, and he died in 10 days :(...I'm a little apprehensive to put another fish in there T_T. It's once again bleaching itself in the sun.
On another note, I think there is a protein film in patches in Bobo's tank fffffffffffffffff *scoops them out*
The goldfish would die in there even with the most diligent of cleanings... They are honest to god quite possibly the messiest fish alive. They poop like there is no tomorrow, so depending on the type, they need a good 20 gallons each as the minimum. In a two and a half gallon tank split between two growing fish, you can't expect them to live to their 10-20 year life expectancy. Also, it's possible your betta died of something that was already wrong with him when you bough him. I say if you want to, give it a good bleach solution bath, rinse well, and try again.
iDed, I'm not sure about the size of your tank for 2 plants, but someone else will know.
cJayBetta, give your fish some time. They can go a while without eating. Give him time and remove uneaten food. Then try again next feeding time. It sometimes takes a while for them to settle in a new place.
Gave him some blood worms this morning and he gobbled them up.
@JKFish: Yeah I know, I actually rescued my first two goldfish from the biology labs at my university, they were actually living in a 0.5 Gal tupperware for a week :(...The second I got a chance to go to the mall I did.
Maybe I will just bleach it again, there are so many adorable bettas that came into my lfs this week >_<!!
I don't know anything else that can go in a 2.5 safely, and I don't want it to just sit around :(
@Betta Slave: I'm no expert, but when my goldfish caught ich from me adding another one, The Ich medicine I used had VERY specific directions on how to use it. It said to use one package per 10Gal every 48 hours until it's all gone. I think I only used 2 packages before all the ich died. It also said on the package that I had to treat the tank (so no moving them to a QT) because of the 3 stage life cycle of ich.
I hope your fishy gets well soon! <33
Thank you :) I've been dealing with parasites a TON lately- everything from gill mites to body flukes, so no worries.
