I have two betta fish, a blue one and a red one. They are in separate 1-2 gallon tanks but are placed next to each other. (pictures below) One picture is how Red looks normally.
They were happy with this arrangement as they were constantly making bubble nests (i read this is a sign of good water quality and happiness). Until yesterday, they began getting really fired up while looking at each other, with their necks flaring and all. Eventually Red backed down and tried hiding and ignoring Blue. Once I saw this put cardboard between the tanks before they got exhausted or it damaged Red mentally.
Then this morning I noticed Red was barely moving and just sitting on the bottom of the tank. His fins were wrinkled and not spread out as they usually are. (picture below) What was weird is that if I come near him he bursts in energy like a spasm then continues to hang around.
I've had both of them for two weeks and they are usually active, but it seems like Blue had thrived and is ready to fight at all times and Red is just slowly wasting away.
Blue is a constant overeater and his belly looks like a little pea sometimes, so I fast him a bit. Because he is a bit more aggressive would it benefit him to have live food?
Red does not eat much at all.. there is always food left in the tank, maybe he doesnt like the food?
I feed them dried bloodworms in flake form twice a day
I am aware the tanks are small but I am keeping up with the maintenance, I clean the tanks every 2nd or 3rd day or as soon as the water is not clean and if there is any uneaten food. They seems pretty happy with it.
Did you know: over flaring can cause stress, sickness, and "blown" fins in bettas? And of course, fin biting too!! This is why I only set my compatible boys side by side (currently only one divided tank!!) while everyone else only gets short flare sessions.
Yes, that is what could be causing it if both were fine before. I've had some bettas go into a depressive mode, stressed mode, and sick mode from flaring - eventually you get to know your betta(s)
Blown fins, refers to when the betta flares a lot, it causes the fins to be stressed, therefore causing tears... Take a piece of paper, and tug on both sides... basically the same concept You're straining the fibers of the paper, causing it to tear.
Those cubes are a half gallon, and not suitable for long term housing for any fish. :/ There are no places to hide in something that small. No plants, no cave, no room to swim really. That can stress a betta out just as much as living next to another betta.
Please excuse my use of the non-metric system as I'm unfamiliar, they are 2litres. I may not be an experienced betta fish owner but I'm not ignorant, I can tell when they're not happy in these cubes. They are fine, they have both been active and healthy since I've been looking after them with the exception of this morning with red.
I'll change their diet to pallets, I want to try brine shrimp but I've been too busy studying to go and locate them in Melbourne.
If one of your fish is not eating, it may be because he is full from previous feedings. More frequent, smaller feedings with variations in food will help. Try to find frozen brine shrimp, it is really really good for them. Bloodworms are considered a treat because the Bettas really llike them, but that is because it's what they eat in the wild. You can feed them bloodworms quite often. Get larger tanks for both (2 gal minimum) and always put the cardboard in there. Food goes flake< pellet < freeze-dried < frozen < live.
Hello and welcome Dsparkles..:) cute name, in any case, I would also suggest changing the diet, and offer some micro pellets they are so much better, and a great staple food, and help to boost color, and energy. If you cannot get the brine shrimp, also the Freeze dried items to tend to expand in the belly, causing bloat..and constipation, so offer the Freeze dried bw's as a treat, maybe 1-2x a week, I have noticed a drastic improvement with a rescue I recently took in, and this lil guy did not eat, so I jumpstarted his appetite with a f/d bw..and now he's on a micro pellet diet 2-2x a day, and his colr is enhancing, and he hopefully will get some energy, and I hope you lil guy is ok, try the micro pellets, it will make a difference. Also the temp of the tanks is 22deg, that is very cold, prob that was celcius? but if you put a themometer on the tank, it would tell you the temp, those tanks are too small to put a heater, but if they are in a warm part of the house, should be ok, but a thermometer will help you to know for sure.:)
