As of nearly two weeks ago I have a single male betta spledens
who has various deformities. He lives in 7gal heated, planted aquarium that also houses a cycled filter and multiple species of snail. He's called Red (for the lack of a more original name), here is a photo of him (please excuse the blue ring, I used that to feed him while he was on flakes to stop them floating everywhere, I should take it out now that he eats pellets):
His aquarium is a bit of a root jungle at the moment; I've had some plant dieback due to negligence on my part and I'm also battling some string algae issues so fertilizers aren't being introduced for a while. Photoperiod has been dropped too. I do a single 50% water change once a week.
I also have a 4gal aquarium that only houses a few snails; it housed my elderly betta, Kaze, until he passed away and is heated, filtered and cycled. I've been adding plant clippings gradually, trying to get it at least somewhat decently planted but inspiration is lacking. Getting a little anxious to put another animal in there but don't really know what. I do a 50% water change on it per week at the moment to make sure water quality stays good for the snails (one assassin snail and lots of bladder, Malaysian trumpet and ramshorn snails).
I used to have immense issues with water changes due to an illness I've had for eight and a half years; water changes still take a lot of strength out of me but they are much simpler and quicker now that I use a squeeze-activated aquarium siphon. It's funny how a simplistic £3 item can make your aquatic world so much more enjoyable and relaxing.
