The Puffer Forum

How large is the puffer now? I tend to feed daily, to a slightly rounded belly, until the fish is about 3" & then start skipping days. As a full-grown adult, I feed 2x/week.

Probably so full he can't move!

Can you get a clearer pic of the front of this fish? Why is his tail all frayed? Water parameters? Tank size? Inhabitants?

It appears many I know are having the same luck--except me!\

BTW, by topping off evaporated water with tap water, you are hardening the water a lot, by adding more minerals. Even with little to no nitrate, weekly water changes are necessary.

Also, keep in mind, crabs/crays are opportunistic feeders--which means when the puffers are sleeping...

Welcome! considering I answer 90% of the posts here (my site--no help) & am in the US, it would be easier to use ones I can understand & not have to convert all the time. Here are some helpful articles for you to read. You'll especially love the last one, being a "Plant Guy"! https...

Actually, small shrimps do fine with DPs. Lots of folks are very successful with cherry shrimp. Don't ask me why! I would be concerned with the fleshy periscope eyes of crabs. Mine don't touch ottos.

They are best kept in a shoal of 6 or more or else as a singleton.

Really, 123L isn't even large enough for a single adult GSP.

Please do not do that. If anything they should add fresh RO water. Your cycle is precarious at best in this seriously overstocked tank.

You can also dose their tank.

Your tank is much too small for these fish & the water will pollute very quickly. Filters do not remove pollution, it stores it. Why would you have her add SW to the tank? What SG is it now?

You don't need foods to fit into their mouth. They have serious chompers to cut into flesh.

How heavily decorated is the tank? When are you upgrading?

What species puffer? If FW, you must treat their food.

How large are those puffers? Filtration? Will you be having someone feeding them?
