He has been doing better and today he ate a betta pellet.
No new plants or new fish added. He was the newest one added back in December.
He has been moved to the 5 gallons by himself (if you exclude the
Amano shrimp in there). The
water parameters there were always negligible even when I was raising the fry. That tank has cycled back in September. The water parameters there are 0 Ammonia, 0 Nitrites, 0
Nitrates,
pH ~7. Temp 75-78 F. I run a Marineland 100 B (good for up to 20 gallons).
The water parameters in the 20 gallons are 0 Ammonia, 0 Nitrites, 10 or 20
ppm Nitrates, pH ~ 8, Temp 80 F. The 20 gallons is due for a water change, I only left the Nitrates to go up to 40 ppm once in its "history". When I do water changes, I remove over 60% of the water every 7 - 10 days. I run a Marineland 350 B (good for up to 70 gallons) and I used to also run a Marineland 100 B as well, but I removed it.
The issue with this fish is that I purposely bought the most depressed looking betta in the store to give him a new home. I noticed that fish was sitting on the same shelf for almost two months. So one day after work I passed by and decided to scoop him up. I had him in a bowl for three days and put
seachem paraguard as he had a little fit rot. He seemed to recover and I added him in the 20 gallons. He started eating two days later and became very active. I fed him blood worms and pellets.. But I also fed the other fish their flakes. This guy would eat his food and eat the flakes of the other fish as well, to the point where he would clean up the tank faster than the
Cories. Obviously, he became bloated and he stopped to gradually eat his own food and lived exclusively on the flakes I was feeding the other fish. This is the point where he started becoming aggressive with the
Black Ruby Barbs and started spending increasing amounts of time hidden. One Barb would nip him as he came out to disrupt their play time. This is when I first considered moving him, but I noticed the fish stopped nipping after I intervened a few times (I know people say it is impossible to discipline fish, but I think some breeds are more intelligent than others and understand when they are doing something that displeases their owner). Thing resumed to normal, except for
flashing and flaring at the
Barbs but he would still come out only to feed on flakes until he stopped and went into a "coma" like state where he lay in the same spot for days. Over a week passed with me trying to figure out what is wrong with him until I moved him. Which is why I became concerned since I was pretty sure he did not eat for over a week.
So I think this was a combination of issues.. Tankmates, food quality, possible flukes, depression prone betta?
