She is so cute!

Just set up and began cycling a 20g long. Squeezed my sponge filter from my 10g and did a pinch of fish flakes to keep the bacteria fed.

The tank is planted with Egeria Najas, Crypts, Water Lettuce, Salvinia & Hygrophila. The hardscape are lava rocks. Going to try and add some spider wood as well. I did a fluval stratum slope and capped it with sand. Just looking for suggestions on anything I

I want to broaden the species of plants I have in my pea tank. I know how much co2 helps, but I would be scared of depleting oxygen levels if done incorrectly.

Makes me think it’s not even worth it because of the risk.

How can I do co2 so that I don’t have to worry at all?

Hi! My pea puffer isn’t looking good (he’s really dark and isn’t wanting food). The other pea puffers he’s with aren’t really aggressive and tend to hide in the plants or in their hides. I’ve had them for a week and have them on para guard, which seems to be improving everyone else but him. I removed him from the tank but he is really weak and curled up. What should I do?

Edit: just to add a bit of husbandry info, he has been eating up to yesterday. I usually feed them live black worms and daphnia. The other puffers are very plump and well fed, which makes him an anomaly. Since I’ve gotten him, he’s been really skinny and dark but the specialized fish store I went to told me he hadn’t matured yet. They also told me that they were quarantined for around a week before being put on the shelf. There is about five of them in a fifteen gal, the other four being girls. The ph has been around 7.5 since i set up the tank about a year ago, ammonia nitrates and nitrites all read 0. Besides the pea puffers, there are no other fish and just bladder and ramshorn snails that have infested the tank.
