Most 10g starter kits don't include what you need to safely cycle water for a betta (test kit, heater, cycling ammonia, siphon).

Ever wondered what your tank is holding back? A 300 litre setup weighs about 350 kg, and glass thickness depends on a tank's height, not its volume. Short doodle animation: youtu.be/IMCVa3THmPs #aquarium #fishkeeping

Here's Little Blue's three FAR larger siblings in the 75 gallon tank across the room. Same brood.

You'd th8nk I was starving them based on their begging but they literally just got fed live brine shrimpnot more than 10 MINITES AGO!

After working on it for almost an entire week, I‘m happy to present you with an update on the new aquarium. Planting is getting close to being done.
I also have some future inhabitants already in the other tanks for the time being.

New to freshwater fishkeeping? Before adding fish, plan the tank, cycle the filter, match fish to your water, and build a weekly care routine. Which step surprised you most? 🐟

2. How much did it change what the filter knew afterwards?

The distinction turns out to be quite useful.

Tap-water nitrate T is modelled separately as a slowly varying Gaussian random walk. That is an assumption, but a more plausible one than treating the supply as perfectly constant.

This is the same mathematics as the “nearly constant velocity” model used in target tracking: N takes the role of position and r of velocity.

My hidden state is

x = (N, r, T)

with r the net accumulation rate and T the nitrate concentration of the tap water.

Two of them recently started a brood, and the others also act as a pair.

Any cichlid experts around here who could give a possible explanation for that? Thanks a lot in advance!
