I was just cleaning my guys this morning and I noticed some differences. Bluey, who tends to blow a lot of bubble nests, generally has this odd oily stuff on the top of his tank. The tank is covered, so I don' t think it's a lot of dust or debris getting there. Anyone else have that? Is it related to bubble nesting? It almost looks like an oil slick and it's definitely nothing I put in the tank.
Crumb, on the other hand, has no oil slick (he doesn't really bubble nest, hence my correlation) but the bottom of his tank tends to have a bunch of junk on it. I vacuum it out once a week but he seems to have more junk accumulating on the bottom, far more than Bluey. Are some bettas messier than others? Does their poop react differently to the water?
I've only had these guys for about 4 weeks so up to now I've been doing 50% water changes regularly with vacuuming once a week (in 3 gallon tanks) with the intention of throwing in 100% changes one a month in order to clean out all the plants, rocks, etc. That would be this week.
Anyone else know why one tank might be getting oil slicks and the other having more junk on the bottom? does 100% once a month (with 50% each week plus vacuum) sound like enough?
Also, i've never just used tap water directly. I always age the water and then use the stress coat (aged at least 2 days). Anyone here just use tap water directly with dechlorinator without aging the water? I've always been a little nervous about that...
