Somehow this fish got into my tank from a decoration he was hidden inside of, I believe he's a spotted talking catfish. Would he be suitable for a community tank because he needs to moved from my 75 gallon. He's very small and I have a crayfish in the tank he's in now and he's already caught him...
Nothing's changed in the tank except I've been adding a biofilm supplement to give them more food to graze so maybe this is what's causing it. If it's nothing harmful it's kinda cool for them to have some color at least.
Mine did the same thing when I added two new pieces , I just kept up with my normal water changes while the shrimps ate it up and nothing bad ever happened. That growth is pretty common with new driftwood pieces
Mollys usually need about 29 gallons anyway but once those fry grow you will be overstocked, plus some of your fish are schooling fish which need about 5-6 of a species so I'd look into upgrading your tank soon.
Didn't think of this before but you said this is new behavior , is their anyway you can test the water parameters? They can produce a lot of waste in a tank that size so you could be having some sort of ammonia spike causing him to try to escape also
It won't be long before he gets out their escape masters but if they're comfortable they shouldn't try to get out. I'd try to set up some type of makeshift screen for him so he doesn't climb out until then.
It honestly could be the size , they are very active creatures that will explore everything he's probably realizing how small his area is. I would recommend at least getting a 20 gallon long this will give him way more space to explore and a glass cover for it is only about 20-25 bucks
