I have a pellet food right now, but the pellets are too little for him since he has gotten bigger. He used to always come up to the top of the tank to eat, but now he hasn't been doing anything. I'm going to try feeding him a frozen food that sinks today and then I will either by Reptomin or HBH based upon what he does. Maybe he wants to eat at the bottom now... who knows. I just hope he starts eating again. He looks so pale and sad...
When he was smaller, I had him in a tank with a Tetra Whisper Internal filter and I had so many problems with it. It stopped working at times, and it would start to vibrate. I had the 10i. I'll probably end up keeping the filter I have for the next few weeks since I bought him a 30 gallon tank with a Whisper EX 45. I'll have time to set it up and put it together in a few weeks.
